证实了位错塞积的存在及其对微裂纹形核的促进作用。
This verifies the existence of dislocation pile-up and its stimulation to the nucleation of microcracks.
这些缺陷包括：包裹物，色心，开裂，台阶面，位错，小角晶界和位错塞积群。
The defects include cracks, color center, inclusions, step-faceting, low-angle boundaries and dislocation pile-up group.
材料疲劳断裂主要是因为试样在交变应力的作用下上产生滑移最后致使位错塞积而导致的。
The main reason for the fatigue fracture of material is that the specimens under action of alternating stress engender slip, finally resulting in dislocation stacking.
