Abstract：

The titanium alloy component with small fillet and variable wall thickness is formed by a new stamping-forging composite process. First, twice deep drawing with R15 mm and R5 mm were conducted, and the processes of twice and three times upsetting the side wall were studied by the finite element software Deform-3D. The results show that the side wall thickening can be achieved by twice upsetting, and folding and interlayer defects appear easily. However, thickening the side wall 3-4 mm and the fillet 8 mm can be achieved by three times upsetting the side wall to control the wall thickness variation less than 1.35. Thus, this technology can reduce the requirement to the equipment tonnage and improve the utilization ratio of material and the quality of parts, which has a promising economic benefit in production.
