crack branching

The micro cracks in matrix propagate along the bainitic ferrite austenite interface. The crack deflection or branching is occurred due to the different orientation of bainitic ferrite.

基体中的裂纹多数是沿贝氏体铁素体-奥氏体界面扩展，不同取向的基体组织可使裂纹偏转或分叉；

Consequently, at the macroscopic crack branching velocity, the experimental fracture surface energy and the fracture surface roughness; have no single value in such materials.

因此，对这种材料在宏观裂纹分叉速度时，实验断裂表面能及断裂表面韧性没有单一值。

Crack defection, crack branching and whisker bridging process may also contribute to the increase of fracture toughness.

断裂韧性的增加是由于裂纹偏转、裂纹分支和钉扎等作用引起。

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。

The observations of micro-structures by SEM and TEM revealed that the reinforcing mechanisms for SiC ( p)/ M composites were mainly crack deflection and crack branching by SiC particles, and for Y-TZP/ M composites microcrack toughening was important.

用SEM和TEM分析材料断口等显微结构，确定SiC（p）/M复合材料中裂纹偏转和分支对强化增韧起主要作用；Y-TZP/M复合材料中微裂纹增韧起重要作用。

It is shown that the strengthening mechanism of the composites are secondly phase strengthening and grain refining, and the toughening mechanism is a synthetic effect in terms of grain refining, microcrack forming, crack deflection and crack branching.
