N2 - Tantalum, like bee metals, exhibits deformation behavior which is substantially influenced by alloying, temperature, and strain rate. Recently. the mechanical response, in particular the high-strain-rate response, of tantalum and tantalum alloys has received increased interest for ballistic applications. In this paper, recent results on the influence of tungsten alloying additions on the mechanical response and starting crystallographic texture of tantalum-tungsten alloys are presented. The stress-strain behavior of three tantalum alloys containing 2.5,5, and 10 wt.% W has been investigated as a function of loading path, tension and compression, and strain rate, 103 to 8000 SMIN. The yield strength and work-hardening rate were found to increase with increasing tungsten alloying content to unalloyed-Ta. Based on measurements of the surface and centerline textures of the Ta-W alloys, no systematic effect of tungsten content on texture was documented. However, due to variations in mechanical behavior between through-thickness and in-plane properties the need for complete through-thickness texture measurements is indicated.
