%X Based on the analyses of hot-deformation mechanism of the steel,a new constitutive equationdescribing the flow stress of steels was derived.The flow stress data of steel 55SiMnVB havebeen determined at 900—1200℃,strain rates of 1—100s~(-1)and true-strain of 0.08—0.8.Anavailable evaluated formula on the flows tress has been obtained by means of non-linearregression.It can express clearly the physical process of hot-deformation.
