Description
Summary:In this paper, the high-temperature deformation resistance of X80 pipeline steel under different hot deformation conditions was studied through the hot compression test on the Gleeble-3500 thermal/mechanics simulation test machine. The relationship among the deformation temperature, the deformation rate, the deformation degree and the deformation resistance was determined. The mathematical model of the deformation resistance for X80 pipeline steel was established finally and had been proved by the regression analysis to have perfect matching precision.
