alloy was tested under low cycle fatigue and creep at elevated temperatures. The dislocation microstructures developed were examined by transmission electron microscopy (TEM). The deformation behavior...High Temperature Deformation of a β''(NiAl) Precipitation Strengthened Ferritic Alloy S.M.Zhu1,S.C.Tjong2 (1.Japan Ultra-high Temperature Materials Research Institute,573-3 Okiube, Ube, Yamaguchi......
fatigue limit at 5×106 cycle. And the C1 and C2 can be assumed as logarithmic normal distribution. Table 2 values of parameters in AASHTO As to the characteristics of the equivalent stress amplitudes..., the diversity is quite prominent under the former 25×106 cycle. With the consideration of the diversity in variable coefficient, the variation of the fatigue reliability indices can be observed......
