The reheating embrittlement of a crack - free steel during post - welding heat treatment
無裂紋鋼的焊后熱處理與再熱脆性The existence of original flaw leading to early destroying of structure could not be predicted by traditional fatigue designing method of steel structure of crane. so it was inevitable that the cranes that were designed according to this method had hidden dangers. many great steel - making plants were worrying about the serving cranes that were bought in the 70 ' s
由於起重機鋼結構中初始裂紋的存在而導致的結構早期失效用傳統的起重機鋼結構疲勞設計方法是無法預測的,因此這種按傳統方法設計出的起重機就難免會存在一些事故隱患,我國大型鋼鐵企業在七十年代購買並使用至今的大批起重機都有此顧慮。Steel cutting surface or shear surface should have no cracks, slag, stratification and the lack of greater than 1 mm prism
鋼材切割面或剪切面應無裂紋、夾渣、分層和大於1 ?的缺棱。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
