Abstract

In earlier works were presented the investigation on transformation plasticity of hardened steel with various amount of carbon and alloying elements. High transforma-tion plasticity was obtained during the first tempering at 450°C temperature when carbon segregates from solid solution and dispersive carbides form. During tempering of high chromium steel, high transformation plasticity is ob-servable during long-lasting heating and during heating repeatedly at higher than 450°C temperatures.The aim of this work is to investigate the kinet-ics of transformation plasticity of high-speed steel at 560 -650°C temperatures using bending specimens. Results of the investigation can be used for smoothing of the de-formed articles during hardening.
