| Abstract: | During the hot forming process of aluminum alloy, microstructure will occur in a series of complex evolution such as grain growth, inhomogeneous deformation, dynamic recrystallization and which will directly affect the comprehensive properties of aluminum alloy. By mastering the physical essence of the microstructure evolution during heat deformation, to achieve the purpose of controlling the microstructure and the properties of the products has been paid more and more attention by the researchers of materials. This paper summarizes the research status quo of modelling of microstructure evolution during hot deformation of aluminum alloy, especially for the multi-scale simulation method, and points out the problems existing in current research and forecast the development trend of modelling of microstructure evolution during hot deformation of aluminum alloy. |
