采用单轴拉伸扫描电镜动态观察技术,对铝铜合金过时效多晶体变形中的剪切带形成和扩展全过程进行了观察,并分析讨论了材料组织对剪切带形成和扩展的影响.
The whole process of the formation and propagation of shear band during the deformation of over-aged polycrystalline aluminum-copper alloy was observed by uniaxial tensile scanning electron microscopy. The influence of material structure on the formation and propagation of shear band was analyzed.
