Effect of Cooling Rate and Modification on the Structure of Cast AlSi17 Alloy

Abstract:

In the paper an effect of alloy modification, the mold material and the heat dissipation on the structure of hypereutectic silumin AlSi17 are presented. The investigated alloy was cast into: a ceramic (ATD), graphite and copper molds. In order to verify the conditions of heat dissipation through the mold, were used an additional cooling agents, such as water and liquid nitrogen. From the obtained ingots were prepared samples, which were stereological analyzed in the Metilo program.
