C. potential method for crack de-tection has been described. Various types of steel specimens including ferritic, fer-rite-pearlitic, martensitic or austenitic etc. have been examined by this method. At-tempts have been made to clarify the different patterns of potential curves associ-ated with the different steels, the relation between the peak values of potentialcurves and the initiation of cracking, and the relation between the increment ofpotential and the crack growth. Factors causing changes on the potential curvesare tentatively discussed. 收稿日期: 1979-02-18      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 谭志捷 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1979/V15/I2/283 [1] Marandet, B. and Sanz, G., Paper presented at the 10th National Symposium on Fracture Mechanics, Philadelphia, 1976．a No related articles found!
