Characteristic fatigue-creep life map of a Fe–Ni–Cr alloy melted in vacuum and in air at high temperature.

Reports on the characteristic fatigue-creep life map of a ferrous-nickel-chromium alloy melted in vacuum and in air at high temperature. Variation of both the fatigue stress and creep stress with the change of the minimum stresses; Examination of the time-dependent strain-stress curves based on deformation and fracture mechanisms; Provision of fracture characteristics for tested casting alloy melted in vacuum.
