Effect of cooling rate and modification on the structure of cast AlSi17 alloy

摘要

In the paper an effect of alloy modification, the mold material and the cooling rate 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 cooling rate 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 Met-Ilo software.
