Abstract
The rate of migration of grain boundaries was studied in two copper-cadmium alloys during recrystallization as well as during normal grain growth. It was found that the two processes can be described using the same grain-boundary mobility. The recrystallization experiments were carried out with various degreesof deformation and with various annealing times and temperatures. Recrystallization diagrams can be rationalized using basic laws of recrystallizationand grain growth. A new type of diagram is presented in which a combination of the time and temperature is plotted along one of the axes. A characteristic degree of deformation is defined below which the stored energy is removed by grain growth rather than by recrystallization. This concept is related to but not identical with, that usually called the criticai deformation.
