摘要：Using the isothermal compression experiment, the article study the flow stress change law in the semi-hot temperature range for Cf53, discuss the change mechanisms of flow stress, and develop a flow stress mathematical model applied to Cf53 steel semi-hot forming based on creep theory and statistical analysis which provides the basis for reasonable controlling of numerical simulation and thermal parameters for Cf53 steel semi-hot forming. The experiment parameter variation of deformation temperature (from 800 degrees to 950 degrees) and strain rate (from 0.1s-1 to 20s-1) have been realized. Pressure, temperature and displacement during deformation are directly recorded by a computer and automatically transformed into the true strain and true stress, and draw the true stress - true strain curves.
