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

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}<110>has a tendancyto 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 ofnon-equilibrium segregation structures of P on orientation change was proposed and em-ployed to interpret the experiment results.
