Stress versus rupture life data for a superalloy are listed below in Table 1. The stresses are given in MPa and rupture life is given in hours. Rupture time (h) Stress 700 C 800 C MPa 500 C 600 C 600 2.8 250.0 0.018 0.72 12.1 0.0005 500 0.004 0.082 0.00205 400 0.011 0.87 I1.0 98.0 300 180.0 2412.0 0.198 200 100 1.10 (a) Make a plot of stress (log scale) versus PLM, where PLM = (T)(C + log10t). T is the temperature in kelvin, t is in hours, and C 20. and Q= (b) Make a plot of the Sherby-Dorn parameter, Psp = log 100,where e = texp(- 340 kJ/mole. (c) Using the two plot obtained from (a) and (b), predict what stress would cause rupture in 100,000 h at 45s0'C? Stress versus rupture life data for a superalloy are listed below in Table 1.
