Paper Title:
Study of Extrusion Process for a Titanium Alloy Tapered Piece
  Abstract

Direct extrusion forming process, two-stage extrusion forming process and composite extrusion forming process were designed for manufacturing a titanium alloy tapered piece. Comparison of the forming loads under the different processes were investigated using Deform finite element method(FEM).Considering the load size, energy consumption and production efficiency, the best extrusion forming process was eventually selected. The result showed that: In the direct extrusion forming process, the maximum load was 11.5MN, and the die life was short; In the two-stage extrusion forming process, the maximum load was only 4.25MN, but it had a poorer effectiveness and higher energy consumption because of two-stage forming processes. In the composite extrusion forming process, the maximum load was only 38.6% of direct forming process, and it had a higher effectiveness and lower energy consumption because of one-stage forming processes.
