Abstract

Recrystallization, grain growth, and particle ripening behaviors of pre-deformed Fe-In alloy specimens in liquid-particle dispersion microstructures were investigated by microstructural observation. Liquid In particles were trapped by grain boundaries of recrystallized grains, and the trapped particles were dragged by the grain boundaries during grain growth. The recrystallization and the grain growth of the αFe matrix were extremely retarded by the addition of In. The controlling diffusion mechanism of the growth of matrix grains and the ripening of intergranular liquid In particles changed from interfacial diffusion between matrix and particles to impurity diffusion through liquid In particles with increasing volume fraction of liquid In particles.
