Thus,when it is practicable by some ways (for example, by certain heat treatments) tochange the composition of the alloy phases without altering the texture of thespecimen, the method of quantitative phase analysis for such a textured specimencan be taken as identical with that for randomly oriented specimens. In cases where the absorption coefficients of the phases in a specimen happento be large, corrections for microabsorption are necessary and such corrections aregiven in the present work. The method mentioned above has been applied to a cold-rolled Fe-25%Mnalloy as well as to certain compacting specimens of Mo-Cu powders with satisfac-tory results. 收稿日期: 1979-02-18      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 林树智 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1979/V15/I2/266 [1] Zevin, L.
