Abstract
In this paper, the influence of deformation rate, deformation temperature and deformation on the grain size of aluminum alloy during hot upsetting is analyzed by means of finite element software and analysis of aluminum alloy material and forging process, and the factors causing coarse grain of aluminum alloy are obtained. The analysis results show that the use of aluminum-zinc-magnesium-copper alloy, isothermal roll forging process, small deformation rate, proper deformation temperature and large deformation amount can effectively reduce the occurrence of coarse grain defects.
