进行了1Cr18Ni9Ti(奥氏体321型不锈钢)的TEM原位拉伸实验,观察到了位错从裂纹尖端的发射、无位错区形成、纳米裂纹形核及位错塞积等物理现象。
3) dislocation free zone
无位错区
1.
A dislocation free zone(DFZ) is formed between crack tip and the inversely pileup dislocations when the dislocation emission and motion reach equilibrium.
结果发现:黄铜薄膜试样拉伸时,裂尖首先发射位错,平衡时形成无位错区和反塞积位错群;裂尖前方较厚区域可以发生孪生变形,形成形变孪晶,微裂纹在孪晶中形核、扩展,导致裂纹呈Z字形扩展;裂尖无位错区也可能形成微孪晶,微裂纹在微孪晶中形核,使裂纹呈不连续扩展;微裂纹也可以从主裂纹顶端连续形核、扩展。

3.
The results show that 1)in precharged specimens,many dislocations can emit from a crack tip followed by forming a dislocation free zone(DFZ) after equilibrium:2)nanocracks nucleate preferable in DFZs;3)microcracks connect with each other,resulting in the brittle cracks,instead of blunting into voids.
