抄録

This experiment was done in order to elucidate the mechanism of deformation at hot working of metals. The α-brass wires were stretched to various amounts of elongations and then quenched in water within 0.01 seconds. These specimens were annealed at various temperatures and investigated on their recrystallizing phenomenon on annealing. The following results were obtained. (1) The temperature of first recryatallization became higher as the working temperature of the specimen became higher. (2) The specimen worked at 840°C did not show any recrystallization phenomenon on annealing after hot working, but showed a vivid migration of grain boundaries. This working temperature involving no recrystallization became lower as the working degree became smaller. (3) In the specimen worked at 840°C, all the twins disappeared but they appeared again on annealing after the hot working. (4) The hot worked specimen has a stronger tendency of abnormal grain growth than that of cold-worked one on annealing, espcially when it was worked at such a high temperature as 840°C.
