This study investigates the mechanical properties of the second phase particles and Mg-matrix in a Mg–8Al-0.5Zn cast alloy by compression of machined micropillars. The stress-strain behavior showed that the Mg₁₇Al₁₂ particles exhibited a sudden and unusual failure after a significant strain burst. The Al₈Mn₅ particles were much more ductile, but also much stronger.

Mg-8Al-0.5Zn合金中第二相颗粒的微柱压缩力学性能评估

这项研究通过机械加工的微柱压缩研究了Mg-8Al-0.5Zn铸造合金中第二相颗粒和Mg基质的力学性能。应力应变行为表明，Mg ₁₇ Al ₁₂粒子在明显的应变破裂后表现出突然而异常的破坏。Al ₈ Mn ₅颗粒具有更大的延展性，但强度也更高。
