Previous studies demonstrated the correlation between the free energy of grain growth and the activation energy of self-diffusion in liquid iron. This problem was further investigated by studying the behavior of the iron grain boundary atoms during plastic deformation and subsequent recrystallization, using a method based on autoradiography of the radioactive Fe/sup 59/ atoms introduced into the system and supplemented by data obthined by x-ray diffraction and chemical and microstructural analyses. In studying the diffusion process, electropolishing and autoradiographic tests were alternated. It was established that relatively high- and also relatively low-level deformations did not cause a substantial change in the structure after a double recrystallization and an alpha yields gamma transformation process. In the absence of recrystallization, the plastic deformation process is accompanied by a considerable transfer of atoms at the grain boundaries and by a novel, nondiffusion type grain-growth mechanism.
