Inner and outer diameter deep profiling heavy titanium alloy ring forge piece and forming method thereof

The invention discloses an inner and outer diameter deep profiling heavy titanium alloy ring forge piece and a forming method thereof, and belongs to the technical field of solid rocket engine joint forming, the inner and outer diameter deep profiling heavy titanium alloy ring forge piece comprises a forge piece, a forge piece outer diameter contour is arranged outside the forge piece, and the forge piece outer diameter contour is transited through a large fillet, so that material flowing during forging is facilitated, and the inner diameter of the forge piece is provided with profiling. According to the profiling design, on one hand, the core position of the forge piece can be forged thoroughly during forging, so that the performance of the core is improved, and on the other hand, the wall thickness of each position of the cross section of the forge piece tends to be uniform, so that the material distribution difficulty during blank manufacturing is reduced, and meanwhile raw materials can be saved to the ma
