多晶X射线线形傅氏分析方法在合金材料力学性能预测上的应用

APPLICATION OF X-RAY PROFILE FOURIER ANALYSIS TO PREDICT MECHANICAL PROPERTIES OF ALLOYS

缺陷组态直接涉及到结构材料的力学性能,特别是位错亚结构(DSS)为最重要的缺陷组态中的第一个。本文评论并叙述了一种由王煜明完善并发展了的关于DSS的实用X射线线形傅里叶综合分析方法。根据此法进行了定量预测合金材料的力学性能,同时证明本方法的实际应用价值。

The defect configuration relates directly to the mechanical behaviour of structural materials. Especially, dislocation substructure, DSS, is one of the most important configurations. In this paper, a realistic x-ray diffraction profile analysis of DSS, developed by Wang, is reviewed and illustrated. Its application to predicting quantitatively mechanical properties is made.
