Some alloys experience an additional solution heat treatment, while other alloys become overaged in the HAZ.

一些合用辅助固热，而有些合在HAZ中度时效。

Effects of master alloy of quasicrystal containing magnesium additions and solution treatment on microstructure and mechanical properties of AZ91 magnesium alloy were studied.

研究了镁基准晶中间合和固工艺对AZ91合显微组织和力学性能的影响。
