自1931年以来，镁合金的过热细化机制一直不明确。根据对高纯和工业纯镁铝合金的细化作用的最新认识，提出了一个模型。该模型解释了大多数关于过热的实验观测结果。分析了不同镁铝合金在过热和不过热条件下的晶粒度随生长限制因子的变化规律，为模型提供了很好的支持。(C)2006 Acta Materialia Inc.由爱思唯尔有限公司出版。保留所有权利。
The mechanisms for grain refinement of magnesium alloys by superheating have remained ambiguous since 1931. A model has been proposed on the basis of the recent understanding of the grain refinement of both high purity and commercial purity Mg-Al alloys. The model explains most of the experimental observations about superheating. Analysis of the grain size data obtained from different Mg-Al alloys as a function of the growth restriction factor with and without superheating provides good support to the model.
