Research progress on the optimization in order to obtain the value of material constants for a set of creep damage constitutive equations was presented, including (1) a brief review of continuum creep damage modeling and the designs of objective functions; (2) case study reporting the influence of the initial start points on the final results; and (3)(More)
Considering heavy forged parts presented that water spray is an appropriate technique as quenching operation. In general, the rapid cooling causes residual stress field due to the dis-homogeneity of the distribution of temperature in the part and the different microstructural phases. In comparison with other conventional quenching methods, spray-quenching(More)
