Abstract
A stretch-forming apparatus includes a main frame which carries a die enclosure between jaw assemblies. An insulated die is mounted in the enclosure. A method of forming a component includes placing a workpiece in the enclosure, heating the workpiece to a working temperature using electrical resistance heating, and then stretching the workpiece against the die. The method is particularly useful for titanium workpieces.
