Abstract:
A 20-month program was conducted to develop improved chemical vapor deposition CVD processes for applying tungsten to the bores of gun barrels, and further, to characterize the physical and mechanical properties of the CVD tungsten as deposited. Conventional and high strain-rate tensile and compression tests were conducted on CVD tungsten as deposited on 4150 steel at temperatures of -65 F, ambient, and 200 F. Density, thermal expansion, and thermal conductance measurements were also made. Barrel materials of 4150 steel, CG-27, L-605, 718, and Pyromet X-15 were investigated. Based on test firings, acceptable CVD tungsten adherence was demonstrated on 4150, but the other four alloys revealed only marginal quality. Fourteen .220 SwiftMG-3 tests barrels of the five materials were fabricated and delivered to the Air Force. Author
