摘要: 用分析电镜及三维取向分布函数(ODF)法,研究Fe—P合金中磷的非平衡偏聚过程与取向变化的关系,结果表明,磷择优偏聚于{110}滑移面上,在450℃以上生成了重复周期为a=1.582nm的磷偏聚结构,合金在回复过程中已发生<001>∥ND取向减弱和<111>∥ND取向增强的变化,及{111}<110>转化为{111}<143>织构的倾向,再结晶后,{111}<143>取向转变为{111}<112>取向,本文提出磷的非平衡偏聚结构作用对取向变化的模型,获得满意解释。

Abstract:Using 3-dimensional orientation distribution function, study was made of theeffect of non-equilibrium segregation of P on the orientation variation in cold rolled Fe-P al-loy during annealing under analytical electron microscope. P is found to segregatepreferrentially on the {110} slip plane. The non-equilibriously sgregated P forms a structurewith repeat cycle a=1.582 nm over 450℃. The fiber texture may vary in decrease of <001>// ND and increase of <001>// ND, and transfer from {111} <110> to {111} <143> withtemperature raising during alloy recovery. After recrystallization, direction {111} <143>changes into {111} <112>. A proposed model about the formation of recrystallization tex-ture was fairly explained by structure of P non-equilibrium segregation.
