The microprocesses of deformation and fracture in 18 - 8 stainless steel were observed by in - situ tension in tem . it was found that the dislocations were emitted from the grainboundary and dislocation source inside a grain and slip along their slip system respectively . partial dislocation could also be emitted from the grainboundary , and moved into the grain , and that leaving behind a stacking fault 摘要浙江人學(xué)博1 :學(xué)位論文采用透射電鏡動(dòng)態(tài)拉伸、原位觀察icrlsnigti不銹鋼形變與斷裂過程,發(fā)現(xiàn)不銹鋼變形時(shí),晶界和晶內(nèi)位錯(cuò)源均可產(chǎn)生位錯(cuò),并沿各自的滑移系運(yùn)動(dòng)。
The width of stacking fault increased as partial dislocations move forward . in the fracture of 18 - 8 stainless steel , many dislocations were emitted from the crack tip during the early stage of crack propagation and moved forward , and then a dfz was formed between the crack tip and the pile - up dislocations . the dfz is an elastic zone 不銹鋼斷裂時(shí),裂尖首先發(fā)射位錯(cuò),并離開裂尖向前運(yùn)動(dòng),裂尖前方留下無位錯(cuò)區(qū),位錯(cuò)反塞積在無位錯(cuò)區(qū)的端部,無位錯(cuò)區(qū)是應(yīng)變很高的異常彈性區(qū),隨著裂紋的擴(kuò)展,無位錯(cuò)區(qū)逐漸發(fā)生晶體碎化和轉(zhuǎn)動(dòng)。
