Question: Steady-state creep rate data are given below for nickel at 1000C (1273 K): If it is known that the activation energy for creep is 272,000

Steady-state creep rate data are given below for nickel at 1000°C (1273 K):
Steady-state creep rate data are given below for nickel at

If it is known that the activation energy for creep is 272,000 J/mol, compute the steady-state creep rate at a temperature of 850°C (1123 K) and a stress level of 25 MPa (3625 psi).

[MPa (ps)] 15 (2175) 4.5 (650) 10- 10r6
