Influence of heats, heat-treatments and testing methods on high temperature fatigue of 2.25Cr-1Mo steels

摘要

Low-cycle fatigue properties for three heats of normalized and tempered 2.25Cr-1Mo steel were investigated under uniaxial strain control at high temperatures. Comparing with the reference data for normalized and tempered, and annealed 2.25Cr-1Mo steels under uniaxial or diametrical strain control, it was clarified that the influence of heats, heat-treatments and the strain control mode.
