The logarithm of total acoustic emission energy is proportional to the logarithm of long range stress, and its turning point corresponds to the point of cracking. Therefore, it seems to be available to determine accurately the state of the cracking tip of these low strength and high plastic alloys by the method.Two kinds of acoustic emission sources were found during the plastic deformation and fracture process of α-Ti: the dislocation movement and the microcracking and growth of a crack. 收稿日期: 1982-03-18      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 朱祖铭 穆在勤 王双全 杨淑华 尹花子 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1982/V18/I3/272 1 Dunegan, H.
