研究了挤压态Mg-Sn-Al-Zn合金的高温拉伸性能。在合金中发现了低温超塑性，在473 K下，在1 × 10−3-1 × 10−4s− 1的应变速率范围内，拉伸伸长率为410-950%。超塑性变形行为归因于细晶组织，其中包含热稳定的Mg 2Sn沉淀物。
The tensile properties of extruded Mg–Sn–Al–Zn alloy at elevated temperature were investigated. Low-temperature superplasticity was found in the alloy, which exhibited tensile elongations of 410–950% at strain rates in the range 1 × 10−3–1 × 10−4s−1at 473 K. The superplastic deformation behavior was attributed to the fine-grained microstructure, which contained thermally stable Mg2Sn precipitates.
