Dependence of the steady-state creep strain rate on stress is given as: ε⋅=Kσn, in which K and n are material constants. Using the figure below (click the link), determine the value of n for the S-590 alloy at 815∘C. steadystate_finer.jpg The figure (attached) shows stress (logarithmic scale) versus steady-state creep rate (logarithmic scale) for an S-590 alloy at four temperatures.
