Abstract：

The forging process of steering engine bracket for TA33 titanium alloy was studied by combining the finite element numerical simulation software DEFROM with experiment. The research results show that through the finite element numerical models with different forging blanks (round bar,round bar which is upset to 280 mm and then flat to 140 mm, square blank of 340 mm×250 mm×95 mm), initial forging temperatures (989-1019 ℃) and forging hammer numbers (1-3 hammers), the optimal forging parameters are obtained with the square blank of 340 mm×250 mm×95 mm, the initial forging temperature of 999 ℃ and the forging hammer number of 2 hammers. Finally, it can be seen from the results of process experiment that the actual forging production is in good agreement with the DEFROM finite element numerical simulation results. The microstructure, mechanical property data and fatigue performance data of the forgings produced by the optimal forging process parameters can meet the expected requirements, and there is a certain margin.
