| Abstract: | An experiment is conducted for the hot metal deformation resistance of high niobium steel by using the Thermecmastor-Z testing machine.The effect of deformation temperature,strain rate and strain on the deformation resistance are then analyzed.The mathematical model is also regressed.It is shown through the results that the model has a feature of favorable curve fitting.The results of the experiment are intended to provide basic data for a feasible operation on the area of austenite control rolling of high niobium steel. |
