Opis

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.

Abstrakt

The paper presents the results of studies of the effect of chromium concentration on the solidification process, microstructure and selected

properties of cast iron with vermicular graphite. The vermicular graphite cast iron was obtained by an Inmold process. Studies covered the

cast iron containing chromium in a concentration at which graphite is still able to preserve its vermicular form. The effect of chromium on

the temperature of eutectic crystallization and on the temperature of the start and end of austenite transformation was discussed. The conditions

under which, at a predetermined chromium concentration, the vermicular graphite cast iron of a pearlitic matrix is obtained were

presented, and the limit concentration of chromium was calculated starting from which partial solidification of the cast iron in a metastable

system takes place. The effect of chromium on the hardness of cast iron, microhardness of individual phases and surface fraction of carbides

was disclosed.
