17. A cylindrical low carbon-nickel alloy was creep tested. The original diameter was 5 mm and the original length was 100 mm. Assume the sum of the instantaneous and primary creep elongations is 1.0 mm. The total length of the test specimen after 4,000 hours is 105 mm. If the test temperature is 427 °C, determine the stress (in MPa) that the sample was exposed to. Show all work The stress versus steady-state creep rate plot for the alloy is shown below. 200 30 20 100 80 60 427 C (800 F) 40 30 538 C (1000 F) 20 10 649°C (1200 F) 8. 107 104 10h Steady-state creep rate h Stress (MPa) (ndot) was
