It was found that such a segregation may cause the intergranular fracture in steel which is confirmed by an Auger spectroscopic analysis. The coefficient of phosphorus segregation α seems to have a quantitative relationship with the deformation ratio θ of steels lgα=A(1/θ~(1/2)), where A is a material constant of working temperature and test condition. In addition, some influences of the local segregation of phosphorus upon the fracture toughness of steels were determined. The average J_(Ⅰc) and K_(Ⅰc) of normal specimens and ones with cracks through segregation region are 9.87 and 7.68 kgf/mm, and 477 and 419 kgf/mm~(3/2) respectively. 收稿日期: 1981-02-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1981/V17/I2/124 [1] 金属研究所,大冶钢厂,H31Mo钢剖锭试验总结,1979． [2] Viswanathan,R., Met.
