This experiment was done in order to elucidate the mechanism of deformation at hot-working of metals. The aluminum wires were stretched to various amounts of elongation at various temperatures and then quenched in water within 0.01 second. These specimens were annealed at various temperatures and their recrystallization on annealing was investigated. The following results were obtained. (1) The mode of deformation at hot-working and the process of recrystallization during annealing of Al wires were much different from those of α-brass wires previously reported by the author. For example,one of the three ways of softening,namely nucleation and growth process, migration of grain boundary and recrystallization in situ, was observed in Al wires. (2) The temperature of first recrystallization became higher as the working temperature of the specimen became higher and as the working degree of the specimen became lower. (3) The hot-worked specimen has a stronger tendency of abnormal grain growth than a cold-worked one on annealing, especially when it was worked at high temperature and low degree of working. (4) The results of X-ray observations corresponded well with the microscopic observations.
