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

o[MPa (psi)) 15 (2175) 104 106 4.5 (650)

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 25MPa(3625psi).

o[MPa (psi)) 15 (2175) 104 106 4.5 (650)
