The activation energy for self-diffusion in copper is 49,300 cal/mol. A copper specimen creeps at 0.002 in./in.
Question:
The activation energy for self-diffusion in copper is 49,300 cal/mol. A copper specimen creeps at 0.002 in./in. / h when a stress of 15,000 psi is applied at 600°C. If the creep rate of copper is dependent on self-diffusion, determine the creep rate if the temperature is 800°C.
