摘要:
测试了MB2/10%SiC复合材料的超塑性,并对不同应变量拉伸试样轴剖面上的空洞进行了观察.结果表明该复合材料呈现出高温高应变速率超塑性.超塑性变形过程中形成大量的空洞,空洞在颗粒/基体界面上形核,其生长服从指数定律.
Abstract:
Superplasticity of MB2/10%SiC magnesium matrix composites was investigated. Fracture surface of superplasticity deformed samples at different amount of strain was also observed. Results show that this composite has the characteristic of high strain rate superplasticity. Large amount of cavity has formed during the superplasticity deformation. Cavity nucleated at the interface of particulate and matrix and its growth rate obey the exponential law.
