从电镜剖面断口试件上很容易观察到裂纹沿晶粒的扩展情况,从而可以确定断裂机制。本文介绍了两种快速制备电镜剖面断口试件的方法
The crack propagation along the grains can be easily observed from the cross-sectional SEM micrographs and the fracture mechanism can be determined. This article describes two methods for rapidly preparing specimens for electron microscopy fracture sections
