Question
A specimen 1015 mm (40 in.) long of a low carbon-nickel alloy (Figure 8.31) is to be exposed to a tensile stress of 70 MPa (10,000 psi) at 427°C (800°F). Determine its elongation after 10,000 h. Assume that the to- tal of both instantaneous and primary creep elongations is 1.3 mm (0.05 in.)
