Study on Heat Treatment Processing for ZL205A Alloy
The heat treat process of ZL205A was studied systematically. According to the experiment data, the conclusions were achieved: The speed of solution treatment of metallic mold casting is higher. The aging temperature affects the aging speed very much. The alteration of the wall thickness caused a difference in microstructure, which affected the solution treatment very much on the same boundary conditions. In the case of solution treatment adequately, the variation of wall thickness almost haven′t any effect on aging.
