【Abstract】 During hot deformation of metal, a chain of complex changes such as grain growth and recrystallisation will happen on its microstructure. This directly influences the manufacturing process and the mechanical properties of the products. The recently development of computer simulation technique of microstructure evolution during hot deformation is overviewed. Several different modeling methods are compared and the responding achievements by different modeling techniques are analyzed.更多还原
