摘要

为研究ZK 60镁合金的热变形行为

对其热/力模拟变形后的试样进行观察

发现变形试样主要有3种:完整型、微破裂型和严重破裂型

产生破裂的试样主要出现在变形温度较低和应变率较高的情况下.比较相应的应力-应变曲线

发现应力值突然下降时的试样表面已开始出现裂纹

即应力-应变曲线形式与变形后试样开裂有关.可见试样的最终形态对分析镁合金的变形曲线有重要影响.

Abstract

To study hot deformation behavior of ZK60 magnesium

the specimen after heat/force deformation simulation was observed.It was discovered that the distortion of specimens mainly have three kinds: integrity

micro bursting and seriously bursting.Cracking of the deformation sample appears under the conditions of lower temperature and higher strain rate.Compared with corresponding stress-strain curve

the cracking on the surface of specimen appears with the stress value dropping suddenly

namely the form of stress-strain curve is related with specimen cracking.Obviously

the final shape of specimen has the important influence on analyzing the distortion curve of magnesium alloy.
