It is resulted that the texture parameter, V_48 is related linearly to Q value. The texture gradient along the direction of tube wall thickness seems to be no appreciable. When the Q value changes from 0.2 to 2.59, the hydride is distributed into a circular direction via radial, and the corresponding texture parameter V_48 decreases from 0.53 to 0.28.The circular hydride distribution may be re-orientated under circular tensile stress after cyclic heat-treatment. The threshold of the stress re-orientaton of hydrideis rather high for tube with radial basal pole texture. 收稿日期: 1986-05-18      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 王超群 郑杰 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1986/V22/I5/142 1 Harris, G.B., Philos.
