ABSTRACT:
Apparatus and related process steps are disclosed for manufacturing titanium alloy sheet metal parts over a die form using radiant heating, particular mechanical motions, and differential fluid pressures in specific sequences of operations. The resulting parts have configurations with substantial depths and are produced both at accelerated rates and with reduced alloy contamination in comparison to known titanium sheet metal forming practices.
