摘要
The moving boundary non-equilibrium segregation duringrecrystallization and the influence of pre-deformation in Fe-30/100Ni alloy at 1000 deg. C was investigated by the PTA(particle trackingautoradiography)technique, optical and electron microscopy. The re-Sults indicated that intensity of boron segregation on movingboundary after different deformation is concerned with thepre-deformation Degree and the moving speed of the boundary. TheTEM(transmission electron microscopy(result showed that thedislocation density Nearby the moving boundary increase obviously.The phenomena are discussed by the widening grain boundary mechanism.
