In this paper, a simulated test was planned to study the formation of coarse grains by means of X-ray diffraction and metallographic observation. Some technological factors which have influences to the formation of coarse grains, such as strain, deformation and quenching temperature, soaking time, etc. have been studied. The causes of coarse grains and their formation mechanismas well as the elimination of coarse grains have been discussed. 收稿日期: 1987-06-18      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 吴宝善 于自尊 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1987/V23/I6/507 No related articles found!
