The Creep Behaviour of a 1% Cr-Mo-V Rotor Steel

Abstract

AbstractCreep tests have been carried out on the three principal transformation structures of a Cr-Mo-V rotor steel which had been given a common tempering treatment. Although creep strength varied with transformation structure, being lowest for martensite and highest for bainite, a single form of σ-έ-T relationship was obtained which can be derived from a solute-drag model.
