Abstract: 
In hot forming process ,the workpiece undergoes plastic deformation at high ‎temperature and the microstructure of the workpiece changes according to the plastic ‎deformation .These changes affect the mechanical properties of workpiece .in order ‎to optimize this process .both the plastic deformation of workpiece and it is ‎microstructure changes should be taken into consideration-since material behaviors at ‎elevated temperatures are usually rate-sensitive , the analysis of the hot forming ‎processes requires a thermo -viscoplastic model. In this paper, by coupling the flow ‎stress prediction model developed with finite element analysis of thermo-viscoplastic ‎of the hot upsetting process, temperature, strain rate, flow stress distributions and ‎geometry of the workpiece at each time step can be calculated .At each time step, the ‎strain rate and temperature at each element are obtained .From these values and ‎history of deformation, the changes in microstructure and flow stress can be ‎determined. ‎
