METHOD FOR FORMING AND HEAT TREATING NEAR NET SHAPE COMPLEX STRUCTURES FROM SHEET METAL

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.

Sheet material forming

A formed sheet metal material (100) and methods, tools (1, 2, 8) and apparatus for forming the sheet metal material (100) in which a pattern of projections and depressions are cold worked in a first portion (101) and, simultaneously, indicia (103) is embossed in a second portion (102) of the sheet material (100). The cold worked portion (101) is formed with the projections and depression configured and distributed such that lines drawn on a surface of the formed sheet material (100) between adjacent rows of projections and depressions are not rectilinear. The indicia (103) is indicative of the alignment between the tools (1, 2, 8).
