摘要：

The influence of preliminary plastic tensile deformation (epsilon(pd) = 9.5-26%) on the low-cyclic fatigue (LCF), phase composition, and residual stresses of 0.3- and 0.8-mm thick VNS9-Sh TRIP steel ribbons is determined. The LCF resistances of the ribbons of both thicknesses are shown to decrease as epsilon pd increases. Cyclic loading is found to lead to the formation of tensile stresses in martensite, unlike static tension inducing compressive stresses in martensite.
