Abstract：A method for clarifying the effect of nitrided case on the fracture of anodular cast iron has been proposed. Assuming that the effect of the nitrided caseis a linear superimposure of the strengthening of matrix in the case and theresidual stress, quantitative expressions of the fracture toughness as well as thethreshold of fracture toughness are achieved. Results obtained from the nodularcast iron appear to be in reasonable agreement with the experimental data. 收稿日期: 1980-04-18      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 胡义祥 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1980/V16/I4/463 [1] 浅见克敏,寺沢正男,吉岡靖夫,日本机械学会论文集 42(1976) ,989． [2] Barson, J.
