| Abstract: | The effects of solid solution treatment and ageing on the mechanical properties and corrosion resistance of a new corrosion resistant casting aluminum alloy were introduced.By means of metallographic observation and EDAX,it was suggested in consideration of phase diagram that the full dissolution and homogeneous precipitation of Mg 2Si phase determine the combined properties of Al 2Mg 3Si alloy in adominant way.In view of the actual application requirements,the corresponding heat treatment system for this alloy was finally established. |
