Title: COLD FORMING OF RAPIDLY SOLIDIFIED ALUMINUM ALLOYS
Abstract:
A dispersion strengthened, non heat treatable aluminum base alloy is cold formed into useful shapes. The shapes are produced using conventional cold forming apparatus. A first sheet composed of the aluminum base alloy is supported by a second sheet composed of a metal alloy having strength and thickness at least equal to that of first sheet. The first sheet overlayed with the second sheet, is then formed to a desired bend radius.
