Abstract

The microstructure, the phase composition, and the mechanical properties of a commercial cast high-temperature ML19 magnesium alloy are studied and compared in the as-cast state and after the recommended heat treatment. In addition to the well-known phases, long-period stacking ordered (LPSO) phases are found to form in the alloy; these phases are characteristic of both the as-cast and heat-treated states of the alloy.

瞬态和热处理态的商用ML19镁合金的结构，相组成和力学性能

摘要

研究并比较了市售铸态高温ML19镁合金的铸态和建议热处理后的微观结构，相组成和力学性能。除了众所周知的相，还发现了合金中的长周期堆积有序相（LPSO）相。这些相是合金的铸态和热处理态的特征。
