Abstract：

An optimization design method of the microstructure in forging process is proposed.The optimal objective is to obtain the fine and symmetrical grain size.The optimal object is the preform shape.The grain size objective function are put forward.The preform shape is used as the optimal design variables.Using the genetic arithmetic and FEM simulation,the software for optimal design method of the microstructure in forging process based on preform design is developed.The preform design of the cylinder upsetting process realizes the optimization of the final microstructure.
