Description

Archives of Foundry Engineering continues the publishing activity started by Foundry Commission of the Polish Academy of Sciences (PAN) in Katowice in 1978. The initiator of it was the first Chairman Professor Dr Eng. Wacław Sakwa – Corresponding Member of PAN, Honorary Doctor of Czestochowa University of Technology and Silesian University of Technology. This periodical first name was „Solidification of Metals and Alloys” , and made possible to publish the results of works achieved in the field of the Basic Problems Research Cooperation. The subject of publications was related to the title of the periodical and concerned widely understand problems of metals and alloys crystallization in a casting mold. In 1978-2000 the 44 issues have been published. Since 2001 the Foundry Commission has had patronage of the annually published “Archives of Foundry” and since 2007 quarterly published “Archives of Foundry Engineering”. Thematic scope includes scientific issues of foundry industry:

  • Theoretical Aspects of Casting Processes,
  • Innovative Foundry Technologies and Materials,
  • Foundry Processes Computer Aiding,
  • Mechanization, Automation and Robotics in Foundry,
  • Transport Systems in Foundry,
  • Castings Quality Management,
  • Environmental Protection.

Abstract

Of great importance in the selection of materials for cast structures is keeping a proper balance between the mechanical and plastic properties,

while preserving the relevant casting properties. This study has been devoted to an analysis of the choice and application of highstrength

aluminium-based alloys maintaining sufficient level of casting properties. The high level of tensile strength (Rm > 500 MPa)

matched with satisfactory elongation (A > 3%) is important because materials of this type are used for cast parts operating in the aerospace,

automotive, and military industries. These beneficial relationships between the high tensile strength and toughness are relatively easy to

obtain in the Al-Zn-Mg-Cu alloys subjected to plastic forming and proper heat treatment. In gravity cast products, on the other hand,

whether poured into sand moulds or metal moulds (dies), obtaining this favourable combination of properties poses a number of research

problems (mostly resulting from the alloy chemical composition) as well as technical and technological difficulties.
