intragranular

In addition, the electron wind force will also enhance the mobility of dislocation groups, that are blocked at the sites of depositional particles, leading to the accruement of dislocations and increases the density of intragranular dislocations.

另外电子风力也会促进被阻塞在沉淀相粒子处的位错团的移动，从而促进了晶内位错的增殖，提高了位错密度。

SEM observations show that the two-dimensional longitudinal section of the intragranular microcracks evolves from the original thin-ellipse shape into the several aligned spherical voids dominated by surface diffusion.

SEM观察表明：晶内疲劳微裂纹纵剖面二维形态发生了主要由表面扩散控制的形态变化，由初始的扁椭圆形演化成多个球洞定向排列的形态；

The concept, formation conditions and formation mechanism of metal matrix intragranular composites were presented. The intragranular composite between α-Al and TiC leads to crystalline fracture.

提出了金属内晶型复合材料的概念、形成条件及其形成机理，分析了其发生穿晶断裂的主要原因是由于TiC与α&Al之间发生内晶型复合。

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。

Many dislocations, intragranular particles, and some thermal strain streaks were found inside the microstructure of the 3 investigated composites, which improve the mechanical properties of the materials.

3种材料微观结构中均发现了大量的位错、内晶型纳米粒子，和一些应力条纹，它们对于材料的强韧化作出贡献。
