Experimental results showed that the SCC susceptibility of the steel in seawater is increased and the CF crack propagation rate, da/dN, is sharply raised with the increase of its YS. For the steels of YS over 890 MPa, tempered less than 650℃, the da/dN vs △K plot appeared a plateau, in which the(dN/da)_(11) kept almost constant and its fracture surface was similar in shape to that of SCC. It is believed that the CF behaviour is close related to the SCC and the SCC Susceptibility of the steel is promoted under the CF condition. 收稿日期: 1986-03-18      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 郑文龙 朱国培 欧阳怀瑾 李革 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1986/V22/I3/95 1 ASTM D1141, (1980) . 2 Engell, H.J,; Baeumel, A., Physical Metallurgy of Stress Corrosion Fracture, Ed.
