Abstract

This work presents an influence of cooling rate on crystallization process, structure and mechanical properties of MCMgAl12Zn1 cast magnesium alloy. The experiments were performed using the novel Universal Metallurgical Simulator and Analyzer Platform. The apparatus enabled recording the temperature during refrigerate magnesium alloy with three different cooling rates, i.e. 0.6, 1.2 and 2.4°C/s and calculate a first derivative. Based on first derivative results, nucleation temperature, beginning of nucleation of eutectic and solidus temperature were described. It was fund that the formation temperatures of various thermal parameters, mechanical properties (hardness and ultimate compressive strength) and grain size are shifting with an increasing cooling rate.

Abstract

The paper presents a method of producing a grey cast iron casting locally reinforced with a titanium insert printed using SLM method (Selective Laser Melting). This article attempts to examine the impact of the selected geometry of titanium spatial insert on the surface layer formation on grey cast iron. The scope of the research focuses on metallographic examination - observation and analysis of the structure of the reinforced surface layer on a light and scanning microscope and a hardness measurement of the titanium layer area. Based on the obtained results, it was concluded that the reaction between titanium insert and metal (grey cast iron) locally develops numerous carbides precipitation (mainly TiC particles), which increases the hardness of the reinforced surface layer and local strengthening of the material. The ratio between the thickness of the support part (grey cast iron) and the working part (titanium insert) affects the resulting layers connection structure. The properties of the obtained reinforced surface layer depend mainly on the geometry of the insert (primarily on the internal dimensions of the connector) and the volume of the casting affecting the re-melting of the insert. A more concentrated structure of carbides precipitation occurs in castings with a full connector insert.

Abstract

The present study evaluates the microstructural features, mechanical properties, and wear characteristics of the newly developed hybrid composite of A356/ZrO2/Al2O3/SiC produced by compo-casting at 605±5 °C, 600 rpm for 15 minutes with less than 30% solid fraction in which Bi and Sn were added separately to the matrix before introducing reinforcements. FESEM micrographs and corresponding EDS illustrated the successful incorporation of particles in the matrix. Fine particles of ZrO2 were observed close to the coarse Al2O3, and SiC particles, along with Bi and Sn elements, were detected at the eutectic evolution region. The A356+Bi/Al2O3+ZrO2+SiC hybrid composite exhibited the lowest specific wear rate (1.642 ×10-7cm3/Nm) and friction coefficient (0.31) under applied loads of 5, 10, and 20 N, in line with the highest hardness (73.4 HBN). Analysis of the worn surfaces revealed that the wear mechanism is mostly adhesive in all synthesized composites, which changed to the combination of adhesive and abrasive mode in the case containing Bi and SiC. Inserting Bi not only leads to the refinement of eutectic Si but also enhances the adhesion between the matrix/particles and improves lubricity. This, in turn, reduces the wear rate and coefficient of friction, ultimately improving the performance of the hybrid composite.

Abstract

The article presents the technology of layered casting with the use of 3D printing to make a frame insert. The insert was made of powdered titanium and then filled with liquid cast iron. The paper presents the results of research, including structure observation and hardness measurements, as well as abrasion resistance tests. The results indicate the possibility of creating a local reinforcement using a frame insert. The resulting casting is characterized by a local increase in hardness and, in addition, an increase in abrasion resistance of the entire surface layer. The quality of the obtained connection depends strongly on the casting parameters.
