Development of a Low-Cost Composite Die Using High-Energy-Rate Forming (HERF).

Abstract

.,FDingle,Gordon K. ;Leach,Joseph E. , Jr;HH-73-76DAAG46-73-C-0028AMMRCCTR-73-43*High energy rate forming, *Dies, Titanium alloys, Stainless steel, Helicopters, Fabrication, Cost, ReductionTitanium alloy 6Al 4V, Steel 321A program was conducted to design, fabricate, and test/evaluate a low-cost composite die system for high-energy-rate forming (HERF) of titanium and high-temperature alloy parts commonly used on helicopters. The composite die design was evaluated by conducting forming operations on seven pieces of 321 stainless steel and eight pieces of 6Al-4V titanium alloy. The composite die met the design objectives of low cost (half that of conventional dies), short lead time (at least half that of conventional dies), and medium life (500 cycles).
