Abstract：

Using finite element simulation software Deform-3D, the forming process of H-shaped component was simulated numerically, and the different dies and blanks with different height-width ratios were analyzed. The results show that adopting closed die forming is favorable for this kind forgings. The grain size, grain uniformity and dynamic recrystallization volume fraction are improved and the forming load is reduced with the height-width ratio of blank increasing. The application of closed die and larger height-width ratio blank forming can better solve the problem of coarse grains, mixed grains and relatively low dynamic recrystallization volume fraction, etc., during the forming of this kind of forgings. Therefore, it is benefit for improving the mechanical properties of this kind forgings and the selection of production equipment.
