NON-EQUILIBRIUM SEGREGATION STRUCTURE OF P IN COLD ROLLED Fe-P ALLOYS AND ITS RELATION WITH TEXTURE VARIATION

摘要

The relations between the non-equilibrium segregation process of P and the change of thetexture in Fe-P alloys have been studied by analytical electron microscope and orientationdistribution 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}110has a tendancyto transform into{111}143texture in recovering process.{111}143direction trans-forms into{111}112direction after recrystalizing.A model to describe the effects ofnon-equilibrium segregation structures of P on orientation change was proposed and em-ployed to interpret the experiment results.
