Austenite Stability and Tensile Properties of Warm-Extruded Trip Steels

Abstract

High austenite stability resulting from a variation of working temperatures during warm extrusion caused insufficient work hardening and a loss of ductility in war-extruded TRIP steel. The austenite stability could be adjusted, however, by a tempering treatment to remove some carbon from solid solution, giving tensile properties equivalent or superior to those obtained by warm rolling. Difficulties in alloy composition control or temperature control during processing of TRIP steels can thus be compensated by a simple final heat treatment.
