摘　　要：对ZL2 0 5A合金的热处理工艺进行了系统的实验研究。根据实验数据得出如下结论:金属型铸件固溶处理速度很快,时效温度对时效速度影响很大;进行固溶处理时在边界条件完全相同的情况下,壁厚不同造成的铸态组织差异对固溶处理有很大的影响;在充分固溶的情况下,壁厚不同对时效影响不大。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.
