The dynamic process of non-equilibrium grain boundary segregation of trace boron in Fe-40%Ni alloy during cooling and the effect of cooling rate were investigated by boron tracking autoradiography technique. The results indicate that during cooling process, the amount of segregated boron on grain boundary firstly increases fast, then enters a comparatively even increasing stage and increases rapidly again at the third stage. The details of each stage varied with cooling rate are explained. When thc segregation develops to a certain degree, the segregated boron atoms transform fiom solute status to precipitate status.
