| Abstract: | During metal hot forming,several processes including nucleation,grain growth,phase transition,and recrystallization significantly influence the microstructure.The microstructure directly affects the manufacturing process and the mechanical properties of the products.Technologies using in current computer simulation of microstructure evolution in hot forming are thoroughly reviewed.Several modeling methods are compared with each other.Finally,the latest research on different simulation technologies are summarized. |
