摘要：

This study aims to investigate the effects of strontium additions on microstructure, the soundness and mechanical properties of AZ91 magnesium alloy. The results show that a small amount of strontium addition to AZ91 significantly increases the density, yield strength and hardness. Microstructure observations reveal that the additions of strontium cause a reduction in the grain size. Small grains improve mass feeding, and hence minimize microporosity formation, or increase in the density, in turn, which result in improving mechanical properties.
