ZL205A合金T5状态过烧的研究

An Investigation on the Overheating of Cast Aluminium Alloy ZL205A -T5

本文研究了ZL205A合金过烧组织特征与固溶温度及时间的关系,对T5状态过烧组织性能的影响。通过特征观察,探讨各种过烧相形成的机理,为在实际生产中如何避免过烧及判断过烧提供参考。

In this paper the effects of solution treatment temperature and time on the overheating structure characteristics and the tensile properties of alloys in T5 condition have been studied. The formation mechanism of overheating phases has been discussed also. It can be a reference to prevent the overheating of castings and to judge the overheating structure in practice.
