摘要
通过对 2 0 Mn Si钢拉伸断口白斑形成机理分析发现 ,拉伸断口白斑是在低塑性区形成的圆形解理脆性断裂区 ,白斑的产生是由钢中夹杂物。
Blaze forming mechanism of rupture section of 20MnSi steel bar in the drawing is investigated. It has been shown that the rotundity brittle cleavage fracture area form the blazes which have a close relationship with the oxide inclusions, evil gas and widmansta ttent structure, etc in steels.
