Abstract
The backward extrusion process of titanium alloy with large length to diameter ratio was simulated for different punch and die shape. The process variables such as initial billet shape, interface friction, contacting time and punch velocity were investigated and compared with experimental results. To make more effectively titanium alloy cup shape forging products with vertical wall, a modified die design which can reduce forging load, prevent sticking with punch and minimize material loss was suggested.
