SEM对试样微观形貌的研究表明，晶粒大小不均匀是这种材料的微观特征。
Research of SEM indicates that the heterogeneity of grain size is the typical microstructure of the materials.
试样内部各部位的应力大小分布不均匀，随应变速率的增大，最小应力值由自由变形的鼓形区域逐步向心部移动；
The effective stress of specimen is inhomogeneous. As the strain rate increases, the minimum stress value moves from the drum-shaped region to the heart of specimen.
由于试样的不均匀性等原因，理论值一般高于试验值。
