Abstract��The rheological curves of martensite ��M�� in 45 steel were measured on a Gleeble-3500 thermal simulator in a warm compression test. The results showed that the flow stress of martensite decreased with the increase of deformation temperature�� and the grain of ferrite ��F�� changed to equiaxed grain. In addition�� the mechanism leading to the above rheological behavior of M tissue was discussed.
