It was found that many dislocations were emitted from the crack tip during the early stage of crack propagation and were driven out of the crack tip area, and them piled up inversely. a closed dislocation free zone ( dfz ) was formed between the crack tip and the pile - up dislocations. keeping displacement constant, the dislocations were still emitted from the crack tip for a while
本文首先系統地研究了工業純金屬（ fe ， al ， ti和mg ）斷裂的微觀過程，發現所研究的工業純金屬斷裂過程裂尖均首先發射位錯，並離開裂尖向前運動、在裂尖留下無位錯區，位錯反塞積在五位錯區的端部，反塞積位錯群一般呈封閉狀包圍無位錯區。 -
Keeping displacement constant, the length of dfz decreased. the less the lattice resistance is, the longer the dfz is. during the crack propagation, the pile - up dislocations may move forward in the previous direction or in another direction which caused shape of dfz changed. the dislocations emitted from the crack tip might pile up in the dfz and can be served as dislocation source in the successive loading
在裂紋擴展過程，反塞積位錯群發生變化，可以沿原來方向繼續向前運動，也可能改變運動方向使無位錯區的形狀發生變化，后來發射出的位錯可以在原五位錯區中塞積，並可作為位錯源在後續的加載中發射位錯。
