The morphology of its high temperature fractogrph is shown as brittle intergranular fracture instead of normal ductile dimple. 收稿日期: 1981-06-18      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 葛云龙 柴寿森 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1981/V17/I6/687 [1] 柴寿森,葛云龙,钢铁,16(1981) ,№.8,46． [2] Yu, J. and McMahon, C.
