Abstract

A method of manufacturing a complex-shaped metal part, including the steps of applying a metallic sheath around a sheet metal workpiece and applying an electric current through the workpiece in the metallic sheath to heat the workpiece. The method also includes shaping the workpiece in the metallic sheath into a complex-shaped metal part while it is being heated. The shaping can be performed between two ceramic dies or using other techniques for forming complex shapes and curvatures into the workpiece. The method then may include cooling the complex-shaped metal part and removing the metallic sheath from the complex-shaped metal part. This method can allow reactive and refractory material to be safely heated without oxidation when heating/forming in air when the workpiece is sealed within a sacrificial stainless steel or nickel alloy envelope to protect the enclosed workpiece.
