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

The paper presents the results of research on the determination of the effect of pouring temperature on the macrostructure of the castings

subjected to complex (surface and volume) modification and double filtration. Tested castings were made of post-production scrap (gating

system parts) of IN-713C superalloy. Tests included the evaluation of the number of grains per 1 mm2

, mean grain surface area, shape

factor and tensile strength. Casting temperature below 1470 °C positively influenced the modification effect. The grains were finer and the

mechanical properties increased, especially for castings with thicker walls. On the other hand, manufacture of thin walled castings of high

quality require pouring temperature above 1480 °C.
