What steady-state creep rate would you predict for alloy


Estimate the activation energy for creep for the low carbon nickel alloy using the following temperature dependence of creep at 55 MPa.

Steady-state Creep Strain Rate (per hour) ----------- Temperature, oC

1 X 10-7 --------------------------------------------------------- 427

8 X 10-6 --------------------------------------------------------- 538

What steady-state creep rate would you predict for this alloy at 600oC and 55 MPa? What useful life would you predict for this component at 600oC and 55 MPa if you can tolerate a maximum of 1% length change for this component?
