Abstract: Isothermal forging processing was applied to improve the coarse grain defects of traditional aluminum alloy forging in the forming of aluminum alloy lower arm. The forging process was simulated using FEM software Deform-3D. The grain size distribution and its changes during the forging process were analyzed. The coarse grain defects is isothermal forging and non-isothermal forging were compared. The forming reasons of coarse grain defects in different parts were discussed. Simulation results show that the isothermal forging processing can obviously improve the coarse grain defects of aluminum lower arm and help to obtain refined and homogenous grain group in forgings.

Key words: materials synthesis and processing technology, coarse grain defect, isothermal forging, grain size, numerical simulation
