It is shown that the zigzag grain boundary may delay the initiation, growth and propagation of crack, as well as may also influence the crack morphology and the fracture mode markedly. Furthermore, the zigzag grain boundary may intensively inhibit the grain boundary sliding and retard the crack joining, thus, force the bulk-grains to take part in more deformation. It displays an important role in the tertiary stage of creep. The creep life to failure of the alloy tested with zigzag grain boundary was increased by a factor of 1/4, and the plasticity was also improved slightly. 收稿日期: 1984-01-18      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 叶锐曾 葛占英 王曰毅 杜宝泉 廖忠义 李力加 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1984/V20/I1/34 1 王迪;叶锐曾;徐志超;苏永安;高良;俞同丰;张润岗;李力加,北京钢铁学院学报(1982) ,№2,47． 2 徐志超;叶锐曾;王迪;张润岗;俞同丰,金属热处理,(1982) ,№6,36． 3 苏永安;高良;叶锐曾,GH 220合金弯曲晶界的研究,北京钢铁学院硕士研究生论文. 4 #12 5 #12 6 Larson, J.M., Metall.
