摘要

研究了Mg-1Zn - 0.15Ca合金在T = 450 ℃均匀退火后的组织特征和力学性能。退火结果表明，锌在晶粒体积中分布均匀。4-12 h退火后晶粒尺寸的稳定归因于边界处球状颗粒的影响。等通道压角使平均尺寸从300 μm减小到3 μm。强度和伸长率分别提高到270 MPa和13%。

Effect of homogenization annealing and equal channel angular pressing on the microstructure and mechanical properties of magnesium alloy Mg-1Zn-0.15Ca

The microstructural features and mechanical properties of the Mg-1Zn‑0.15Ca alloy after homogenization annealing at T = 450 °C are investigated. The annealing is shown to result in a homogeneous distribution of zinc in the grain volume. The stabilization of the grain size after annealing for 4–12 h is attributed to the influence of globular particles at the boundaries. The equal channel angle pressing reduced the average size from 300 μm to 3 μm. This provided an increase in strength and elongation to 270 MPa and 13%, respectively.
