When the classification of internal stress is based on the model suggested by Macherauch, the second kind of internal stress in the crystalline should be associated with the statisticdeviation of strains in various grains with respect to macro-strain.The value of macro-strainleads to the evaluation of the first kind of internal stress. However, in some cases micro-strainalso results in the peak shift of X-ray diffraction profile. Therefore, besides of peak broadening,one should keep an eye on the effect of dricro-strain on peak shift when microstress is evaluated.The peak shift part stands for the average value and the peak broadening stands for its deviation. Key words： internal stress    microstress    pseudo-macrostress    X-ray method      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 张定铨 何家文 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1998/V34/I12/1273 1 1935;4(6):688(Daviginkof N N Industrial Laboratory, 1935i 4(6): 688) 2 Greenough G B.J Iron Steel Iust, 1951; 169: 235 3辛岛诚一,岛谷幸治,一柳肇材料,1963;12:848(Karashim S, Shimatani K, Hitotssuyanagi H.
