Abstract
A small amount of impurity has a significant effect on retarding the m otion of grain boundaries during recrystallization([1]) Kasen([4]) has investigated the recrystallization and grain growth in dilute allumin ium alloys by measuring residual resistance. The results indicated tha t the solute atoms could be absorbed constantly by migrating boundarie s. In the present work, boron segregation near moving boundaries durin g recrystallization in Fe-30%Ni alloy is investigated by means of part icle tracking autoradiography (PTA) technique. The alloy beeps single phase with f.c.c. structure during quenching. It is important to avoid the influence of phase transformation on the microstructure and boron distribution.
