Popis:	It is well known that the spheroidization of pearlite in eutectoid steels can be greatly accelerated by deformation either before or during annealing. An investigation of the phenomenon by electron microscopy is described and several factors influencing the spheroidization process are reported. Some of the observations confirm suggestions made by earlier workers but other mechanisms are also proposed. In particular, the ability of the cementite to undergo considerable plastic strain at all temperatures investigated is shown to be an essential feature of the acceleration of spheroidization by deformation.
