Upgrading the alloy AlSi6Cu4 (AK64) cast to the ceramic mould

Dudyk M., Asłanowicz J., Ościłowski Ł.

Archives of Foundry Engineering

2007

Vol. 7, iss. 4

43-48

In this article are presented the results of study on the kinetics of the crystallization processes in the refined, modified and filtered Silumin containing copper and the metallographic analysis of the obtained structures. Impact of the upgrading processes - refining, modification and filtration - of the studied alloy AK64 on changes of the impact strength KCV of the cast samples. Original metallographic analysis of the foam filters cast with the studied alloy was carried out. The efficiency of filtration mechanisms on improvement of quality and usefulness of the cast Silumin was demonstrated.
