Abstract

The hypoeutectic aluminum alloy AlSi5Cu2Mg is used for the production of high-strength automotive components such as cylinder head castings. AlSi5Cu2Mg alloy is characterized by a specific chemical composition (low permitted Si and Ti content) determined by the supplier. Due to the low permitted Ti content it is impossible to refine the grain structure of this aluminum alloy using standard grain refiners based on Al-Ti-B. Al-Si-Cu-Mg alloys are thermal stable up to the temperature 200°C, due to the presence of strengthening precipitates. Due to the downsizing, the operating temperature exceeds the temperature of 200°C, which leads to a decrease in the mechanical and physical properties of Al-Si-Cu-Mg alloys. The aim of this study is to analyse influence the alloying elements and heat treatment on the selected properties of AlSi5Cu2Mg alloys that are crucial for cylinder head castings. The paper focuces on the evaluation of the influence of selected alloying elements Sr, Zr and Mo on mechanical and physical properties. The present work also analysis the effect of heat treatment T6 on selected properties and structure of AlSi5Cu2Mg alloy modified by Sr, Zr or Mo. Sr, Zr and Mo were added into the AlSi5Cu2Mg alloy in the form of master alloys AlMo10, AlSr10 or AlZr20. According to the findings, the incorporation of the chosen alloying elements did not result in a substantial improvement in the mechanical and physical characteristics of AlSi5Cu2Mg alloy, which would be critical for its practical application. Physical and mechanical properties noted positive increase due to the effect of thermal processing T6.

Abstract

This study deals with the effect of magnesium content in Al-Mg-B alloy (with a boron content of about 5 wt. %) on the formation of intermetallic phases and elimination of inclusions in the form of boron powder particles in the final structure. At first look, the high melting temperature difference between pure aluminium (660°C) and boron (2076°C) appears to be a potential problem. Moreover, boron has a minimal solubility in aluminium (0.055 wt.%) and the liquidus temperature increases very rapidly with increasing boron content (liquidus temperature approx. 1 160°C at 5 wt.% for Al-B binary alloy). Alloying with magnesium results in the transformation of the intermetallic phases AlB12 and AlB2 to the (Al, Mg)B2 phase and has a significant beneficial effect on the formation of intermetallic boron phases in the aluminium alloy without residual boron powder particles.

Abstract

The paper describes the design of conformal cooling of an aluminium die-casting mold component using numerical simulations along with validation under industrial conditions. The subject of modifications was the insert. The insert comes into direct contact with the metal during the filling of the mold and solidification of the casting and determines the internal shape of the casting. The aim was to optimize the operating temperatures of the insert, reduce thermal stress in the most exposed area, achieve a more even distribution of temperatures in its volume, and maintain the casting quality. Shape modifications were made by topology optimization to reduce the volume of the insert and achieve material savings. 3D printing was chosen as the production technology due to the wider possibilities regarding the variability of the shape of the internal cooling channels. Three geometric designs of the insert were created, and numerical simulations of the temperature field of the mold were carried out in ProCAST software for each variant. Numerical simulations were validated through the temperature field of the mold detected by a thermal camera during the casting cycle. Based on the results, the final design D was selected, for which a complete numerical simulation was performed, including the filling and solidification of the castings. The results were compared with the original variant A. By adjusting the cooling, temperatures were reduced in the most temperature-exposed area of the insert. The new insert variant D showed higher temperatures in the rest of the volume, resulting from material volume reduction. However, the temperatures became even, and the temperature gradients that existed in the original insert variant A were reduced. The simulation also showed that changes in the temperature field of variant D will not negatively affect the quality of the castings. The component will be manufactured and tested in operational conditions in the next research phase.

Abstract

This paper discusses the ability to apply the test method using a scanning electron microscope (SEM) together with EDS (Energy Dispersive Spectroscopy) analysis to assess the quality of fresh chromite sand delivered by various suppliers to Huta Małapanew Sp. z o.o. The research was initiated due to the non-cyclical occurrence of surface casting defects, i.e. pitted skin and burn-on of chromite moulding sand for cast steel casting. The scope of studies comprised the quality assessment of sixteen chromite sand batches delivered for six months by two suppliers. The analysis of the results obtained was used to describe components of the tested chromite sand batches and develop criteria for their quality assessment, considering the chemical composition of chromite grains and the amount of impurities in the form of silica sand and the binder particles. Moreover, clear suggestions were developed concerning the ability to use the given chromite sand batch as the base of moulding sand made in Alphaset technology in Huta Małapanew Sp. z o.o.

Abstract

The subject of the presented research is the influence of molybdenum on selected properties of alloys that are based on the Al-Cu system. It could be observed that the introduction of molybdenum to the multi-component alloy at levels of up to 0.5 wt.% showed increases in the degrees of undercooling ΔT along with the increasing contents of the introduced element. The addition of molybdenum contributed to the reduction of the size of the primary grains of the α(Al) phase. Molybdenum improved the strength of the alloy while achieving elongation at a significant level. This is an element that occurs in the alloy – both in the iron-manganese phases and in the segregates inside the grains. Most of the iron-manganese phases occurred in a more spheroidal form. Additionally, tests were carried out on higher molybdenum content in the alloy. The addition of the tested chemical element at a level of 1 wt.% caused the precipitation of the phases that contained molybdenum, which did not dissolve after heat treatment.

Abstract

Binder jetting technology (3D printing) in the production of foundry molds and cores is becoming more and more industrially used due to ensuring very good quality of the casting surface. In 3D printing technology as the matrix, quartz sand is mainly used, with a grain size of 0.14-0.25 mm. The binder is an organic binder - most often furfuryl resins. As part of this work, self-hardening molding sands with furfuryl resins dedicated to the classic production of molds and cores, as well as molding sands with resin dedicated to 3D printing, were tested. The aim of the research was to compare the viscosity of binders and the properties of molding sands prepared based on binding systems both dedicated to the classic production of molds and cores and for 3D printing. Tests were carried out on the binding kinetics, bench life, strength properties, permeability, abrasion and hot distortion of molding sands prepared on the basis of a standard medium grain matrix and sieved fine-grain matrix. The carried-out tests have shown that the binding system based on furfuryl resin elaborated for 3D printing of molding sands provides strength properties of the sands similar to the classic system of binding self-hardening molding sands with furfuryl resins. However, it ensures faster binding speed and greater thermal stability measured by the hot distortion parameter. The use of a fine-grained matrix results in a decrease in the strength properties of all the molding sands. On the basis of the results achieved for molding sands with organic binding system, a new inorganic binding system was elaborated.

Abstract

conventional alloys are based on a majority of a primary element with some number of added elements, HEAs are based on multiple (usually more than 5) elements that reach equimolar/equiatomic content. With the right combination of elements, properties can be achieved that could predispose HEAs for practical applications.
In the fabrication of HEAs in previous research, pure metals have been predominantly used as the charging material. However, the use of common industrial charge with limited purity is crucial for the more economically viable use of HEAs in industry. Such a charge material may contain accompanying elements which may have an undesirable effect on the properties of the alloy. In order to achieve optimum alloy properties, it is necessary to minimise their content using various metallurgical processes
The aim of the work was the metallurgical processing of CoCrFeNi alloy melted from scrap metal in an induction furnace. The desired reduction of carbon (to 100 ppm) and nitrogen content (from 660 to ~60 ppm) was reached by using carbon reaction under vacuum. Significant reduction in oxygen content (to ~120 ppm) was reached after a deoxidation with aluminium and slight reduction in sulphur content (~25%, to 120 ppm) was reached after a desulphurisation with rare earth metals.

Abstract

Currently, great emphasis is placed on the production of castings with complex shapes. The hybrid investment casting technology using 3D printed models offers new possibilities in the production of such complex and thin-walled castings. The motivation for this paper was to find a solution to the problem with ceramic shells cracking during the 3D model firing stage. The main factors affecting the shell cracking are the thermal expansion of the model and the shell material, and the newly considered pressure of the gas closed in the ceramic shell cavity.
First, thermal analyses were performed of a commercial material used for 3D printing - Polymaker PolyCast™. The characteristics yielded by the measurements helped establish the glass transition temperature, the autoignition temperature and the behaviour of the gas produced by the model burning. Suitable experimental models in the shape of tetrahedrons were designed and used for a number of experiments. The tests confirmed that cracks only occur during shock firing in models printed by the FFF technology with 0% of infill. A solution suggested for further experiments is purposeful venting of the models. Practical testing of the optimization has also been performed. The last step was measurement of the heat transfer through the ceramic shell after being placed in the annealing furnace. There were temperature evolution profiles in the system model-ceramic shell obtained.

Abstract

This paper presents the results of measuring moisture migration in the surface layer of a sand mould during the soaking and drying processes of protective coatings. In the introduction, the process of moisture exchange between the surroundings and the moulding sand is briefly introduced, and the flow of moisture in porous materials is presented. Since the aim of the research is to understand the mechanism of the penetration and drying processes of a protective coating that is applied to a core or mould, the purpose of protective coatings and the consequences of poor drying are presented. During the research, a novel test rig was used to measure the resistance of a porous medium due to moisture migration. An alcohol-based zirconia coating with a conventional viscosity of 20 s was used for the tests. The viscosity of the coating was determined by using a Ford cup with a mesh clearance of 4 mm. The cores for the tests were made from a phenol-formaldehyde resin moulding compound. The average grain size of the sand matrix was dL = 0.25 mm. During the core preparation, pairs of electrodes were placed in the mass at depths of 1, 2, 3, 4, 5, 8, 12, 16, and 20 mm. The resistance was measured continuously. During the tests, the moisture-migration process in the top layer of the core was determined after the protective coating was applied to it. The tests were conducted in a climatic chamber with air temperatures of T = 25° and 35°C and humidity levels of H = 39 and 80%.

Abstract

In current studies, the authors examined the influence of ultrasonic vibrations on the solidification of Zn – Bi 2% alloy. The research reveals that ultrasonic vibrations have a sufficient influence on the crystallization process. In the case of both groups of ingots (Zn and Zn-2%Bi), the differences in microstructure and mechanical properties could be observed. The methodology was based on the casting of two samples from the same ingot form with identical configurations. One of the samples was used as the reference (cast without ultrasonic) and the other to examine ultrasonic vibrations' influence. Casting with ultrasonic vibration was carried out with a frequency of 35 kHz. Sonotrode was located on the underside of the designed crucible. The samples were circular shape with a diameter of 50 mm and a thickness of 10 mm. A tensile compression test, Vickers microhardness test and microscopy analysis were performed. The results showed enhanced organization of microstructure and the fragmentation of grains in the case of the ingots with the ultrasonic vibration presence.

Abstract

Using the numerical modelling, the movement of the solid phase in the form of concentrate particles was analysed in the space of the reaction shaft and in the settler of the flash furnace. The calculations were carried out using a two-phase flow module. It was found that for all analysed concentrate particle sizes their share in the reaction shaft decreased over time. The particles moved in the form of one stream extending along the reaction shaft, accumulating on the side walls of the shaft and settler. Vortices were formed in the region of the settler tub containing particles to the upper spaces of the reaction shaft. The proportion of concentrate particles along the center of the reaction shaft after 60 s is 70 μm 1% - 3% for particles, 80 μm 0.1% - 0.7%, and for 100 μm 0,2m 0.2% - 0.7%. Along the side walls of the shaft, the shares of 70 μm particles varied between 40% and 9% over a shaft length of 5.5 m, and over 1.5 m from 12% to 10%. For 80 μm particles, the shares were 5% to 1%. The shares of 100 μm particles over a length of 1.5 m varied between 7% and 3%, and over a length of 5.5 m from 7% to 2%. Along the 70 μm reaction shaft, the concentrate particles moved the fastest at a speed of 8 m/s to 0.23 m/s. The 80 μm particles moved fastest in the range of 13 m/s to 3 m/s, and the 100 μm particles from 0.4 m/s to 2 m/s.

Abstract

This paper presents and describes the research capabilities of a prototype experimental bench for realising the composite processing of liquid aluminium alloys by involving gas refining by rotary degassing technology and refining with salts (fluxes) in powder form.
The constructed unit was installed in the Experimental Foundry of the Faculty of Foundry Engineering at AGH in the Department of Moulding Processes, Mould Technology, and Non-Ferrous Metals Foundry; it is an integral part of a thyristor-based medium-frequency induction furnace with a melting capacity of up to 60 kg for aluminium alloys. The new experimental bench performs barbotage refining using a rotating head with the possibility of alternating the introduction of refiners/modifiers in powder form. This method can be used in casting lines: continuous in reactors, or batch in ladles.
The innovation of the design of the stand and the treatment of the liquid metal with powdered additives consists of dosing the refiner fluid deep into the metal bath through a channel that was made in the rotor axis and the head; this differs from conventional methods in the small amounts of introduced salts and, at the same time, in the very good metal-inert gas-salt homogeneity of the treated metal bath. This method of dosing the refining salts increases the efficiency of their use, reduces any losses, and limits the formation of post-refining slag (thus, minimising the negative environmental effect). The feedstock that was used for the test smelts consisted of recycled materials: aluminium 99.7 (in the form of wires of various cross-sections that were used in electrical engineering – so-called ‘SECTOR’), and the sub-eutectic AlSi7Mg0.3 alloy (in ingot form). The scope of the tests included verifying the technical solutions that were adopted for the dosing of the bulk materials in the form of a fluid, selecting the melting temperature, and dispersing (distributing) the materials in the bath via the rotor head. The results of the trials were reviewed in terms of the changes in the hydrogen content of the performed process and information on such powder-flux-introduction parameters as the type of the rotor head and the melting temperature of the powder flux. Preliminary trials showed that the performed complex refining (rotary degassing + refining with salts being blown as a fluid into the lower parts of the liquid metal) allowed us to reduce the hydrogen content to a level that could not be achieved by gas refining alone.

Abstract

This paper presents a novel technology for the production of a casting material, which is an “in situ” composite on an ADI iron matrix reinforced with titanium carbide particles. As a result of the initiated Self-propagating High-temperature Synethesis reaction in Bath (liquid metal) of the type “solid Ti” – “solid C” type, led to the formation of ceramic phases in the form of titanium carbides. This method, allowed the synthesis of a cast composite based on ductile cast iron and, after subsequent heat treatment, the transformation of this material into ADI cast iron. The greatest advantage of “in situ” composites is that they are produced in a one-step metallurgical process, which is characterised, among other things, by: high thermodynamic stability, synthesis of a reinforcing phase in a metal bath, small size of ceramic particles with the possibility of controlling their dimensions by reaction kinetics parameters during the synthesis process. In this study, metallographic analysis of the composite obtained, both in the initial state and after heat treatment, was carried out using optical and scanning electron microscopy. An analysis of the chemical composition in the micro-area was carried out using the EDS method, the chemical composition was studied using the XRF spark X-ray fluorescence method, and the proportion of graphite and the carbide phase, i.e. titanium carbide TiC, was determined. The results obtained confirmed the possibility of obtaining the composite material via the SHSB reaction route. The heat treatment results showed that the carbides are thermodynamically stable and do not dissolve at temperatures designed for the production of ADI cast iron. The SHSB reaction guarantees a uniform distribution of titanium carbides on the ADI cast iron matrix.

Abstract

The article presents the research results of fume morphology derived from arc welding of stainless steels of 1.4301 and 1.4828 grade. The analysis was performed using laser diffraction and high-resolution scanning electron microscopy. Welding fume has been classified by the International Agency for Research on Cancer (IARC) as a group of agents with proven carcinogenic effects to human. The assessment of the risk related to exposure to welding fume emission depends on the amount of fume generated, its chemical composition and morphology. The combined analysis of these factors determines the toxicity of fume and its impact on the human body. The results of the fume particle size distribution and the analysis of the shape and chemical composition using SEM with EDS in connection with the determination of the fume emission rate enable to obtain an overall assessment of the health risk as-sociated with welding fume. Such assessment is particularly important during welding processes of corrosion-resistant steels, due to the presence of chromium and nickel compounds in the fume, which are classified as substances with proven carcinogenic effects to human (Group 1 according to IARC guidelines). It was found that 15-17% of particles deriving from arc welding belong to the respirable and tracheal fractions, which are the most harmful due to the penetration beyond the larynx.

Review Procedure


The Review Procedure for articles submitted to the Archives of Foundry Engineering agrees with the recommendations of the Ministry of Science and Higher Education published in a booklet: ‘Dobre praktyki w procedurach recenzyjnych w nauce’ (MNiSW, Dobre praktyki w procedurach recenzyjnych w nauce, Warszawa 2011).

Papers submitted to the Editorial System are primarily screened by editors with respect to scope, formal issues and used template. Texts with obvious errors (formatting other than requested, missing references, evidently low scientific quality) will be rejected at this stage or will be sent for the adjustments.

Once verified each article is checked by the anti-plagiarism system Cross Check powered by iThenticate®. After the positive response, the article is moved into: Initially verified manuscripts. When the similarity level is too high, the article will be rejected. There is no strict rule (i.e., percentage of the similarity), and it is always subject to the Editor’s decision.
Initially verified manuscripts are then sent to at least four independent referees outside the author’s institution and at least two of them outside of Poland, who:

have no conflict of interests with the author,
are not in professional relationships with the author,
are competent in a given discipline and have at least a doctorate degree and respective
scientific achievements,
