Abstract:

The equations of the theory of rate processes are applied to stress rupture for predicting the experimental stress and temperature dependance of the time for rupture for three heat-resisting alloys. Results indicate that stress may have an effect on the crystal structure by causing a phase change. It also appears that the same rate-process mechanism is responsible for both transcrystalline and intercrystalline failure and that a correlation may exist between stress rupture and creep.
