Abstract
The microstructure, mechanical properties, and heat resistance of the laminated composites fabricated by high-pressure diffusion welding of a packet comprising alternating foils of niobium alloy with 5, 10, and 15 at % vanadium and aluminum are studied. The alternation of viscoplastic Nb–V alloy layers and strengthening aluminide layers is found to provide a high strength of the composites at 20–1300°C, which increases with the vanadium content in the alloy.
