surface of fracture

The surface of delamination crack is of cleavage fracture appearance with large cleavage face.

分层裂纹表面为解理形貌，解理面较大。

The fracture surface indicates that the mechanism of the superplastic deformation in AZ91 alloy is controlled by the grain boundary sliding accompanied with cavities interlinking.

大晶粒AZ91合金的超塑性变形机制是晶界滑移控制下的孔洞连接协调机制。

This situation caused by broken belt pressure-sensitive labels, backing sheet of the fracture surface as denticular.

这种情况引起的贴标断带, 底纸的断裂面为锯齿状.

The quantitative calculation method for the parentage of the fibrous fracture surface was studied.

考察了断口纤维断面率的定量计算方法.

The mechanical property of N80 steel has increased obviously after adding corrosion inhibitor, where the ductility of N80 steel increased, and crack fissure of fracture surface decrease.

添加缓蚀剂后使N80试样的韧性有明显的增加，断口裂纹缝隙明显减小，力学性能有了明显的提高。

It is found that intragranular structure is formed, and the tortuous routes of crack propagation and the branching, deflecting and bridging are also observed on the fracture surface.

通过对其断口的观察，发现形成了晶内型结构，并观察到了裂纹曲折的扩展路径以及裂纹的分叉、偏转、桥联，这些有助于材料强度和韧性提高的现象。
