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。

The relations between the non-equilibrium segregation process of P and the change of the texture in Fe-P alloys have been studied by analytical electron microscope and orientation distribution function.It was shown that P segregated preferentialy on the{110}slip planes, the P segregation structures with repeating cycle a=1.582 nm form at 450℃.<001>// ND direction abated.<111>//ND direction heightened.And{111}<110>has a tendancy to transform into{111}<143>texture in recovering process.{111}<143>direction trans- forms into{111}<112>direction after recrystalizing.A model to describe the effects of non-equilibrium segregation structures of P on orientation change was proposed and em- ployed to interpret the experiment results.
