摘要

在模角Φ=120°的模具中

对ZE10镁合金以BC路径进行了等通道转角挤压（ECAP）试验

对各道次挤压后试样的微观组织及力学性能进行了研究。结果表明

随着挤压道次的增加

晶粒显著细化。挤压道次较少时

显微组织为细晶（1

μm）+粗晶（约20μm）的混晶组织;挤压8道次后

显微组织比较均匀

细晶晶粒大小为1

μm;挤压12道次后

等轴晶晶粒大小为0.5

μm;随着挤压道次与总应变的增加

力学性能显著提高。

Abstract

The microstructure and tensile behaviors of ZE10 magnesium alloy prepared through equal channel angular pressing （ECAP） by Bc route in the die with a intersecting angle of 120° between channels were investigated.Results indicated that

the grains were refined effectively by increasing the process passes.The initial process passes brought about an unhomogeneous grain structure including fine grains of 1

μm and coarse grains of about 20 μm.When the process passes were up to 8

the alloy’s microstructure became visibly uniform with fine grains of 1

μm.After 12 passes

the alloy acquired uniform equiaxed grains structure with the grain size of 0.5

μm.The mechanical properties were improved effectively with the increasing of pressing passes and the total strain.
