Аннотация
Low-cycle fatigue (LCF) of VZh175 superalloy has been studied at symmetric and asymmetric deformation at room and high temperatures. The effect of the asymmetric cycle on the limit of LCF to a large extent depends on the choice of the parameter describing the given deformation. A transition from the variation of deformation Δε to the maximum deformation of cycle εmax at asymmetric deformation manifests itself in a significant increase in the LCF limit.
