Abstract

The present invention is a plastic working method for austenite containing steel material wherein: a site at which fracture during plastic deformation of the steel material is predicted is specified; the strain ratio ßx of said predicted fracture site is analyzed; the steel material is heated so that the local temperature T satisfies Formula (1); and the post heating steel material is plastically deformed. T is the maximum strain induced transformation ductility temperature with respect to the strain ratio ßx in °C units sL is the standard deviation of the strain ratio ßx dependent equivalent critical strain approximation curve that is on the low temperature side of T sH is the standard deviation of the strain ratio ßx dependent equivalent critical strain approximation curve that is on the high temperature side of T and T is the local temperature at the predicted fracture site in °C units. T 2×sL = T = T+1.25×sH (Formula 1)
