Book excerpt: Tantalum, like all bcc metals exhibits deformation behavior 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, 10ā3 to 8000 sā1. The yield strength and work-hardening rate were found to increase with increasing tungsten alloying content compared 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, a need for complete through-thickness texture measurements is indicated.
Book Synopsis Influence of Boron Additions on Physical and Mechanical Properties of Arc-melted Tungsten and Tungsten - 1 Percent Tantalum Alloy by : Peter L. Raffo

This book was released on 1966 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of boron additions on the physical and mechanical properties of arc-melted tungsten and a tungsten -1 percent tantalum alloy were investigated. Boron additions significantly refined the arc-melted grain size of tungsten. The 1-hour recrystallization temperature was initially increased by small boron additions (approx. 0.01 atomic percent boron), after which it decreased continuously with increasing boron content. High-temperature tensile tests showed that the boron additions produced an initial rapid rise in strength followed by a leveling off of the strength-composition curve. Boron in solid solution was postulated to be the cause of the rapid increase in strength.

Available in PDF, EPUB and Kindle. Book excerpt: In mechanical tests of tantalum-tungsten alloys with nominal tungsten contents between 0 and 10 wt % for strain rates between 0.000016 and 6800sā1 and temperatures between 77 and 400 K, the addition of tungsten noticeably reduces the strain-rate dependence of the flow stress of tantalum near yield. It also subtly alters the strain-rate behavior of the work hardening, making it more like that of copper, an fcc metal. These effects are reflected in the limiting strains for uniform plastic deformation calculated from our flow curves. For unalloyed tantalum, the instability strain appears to drop dramatically for strain rates in excess of approximately 0.005sā1, whereas for tungsten bearing alloys, it remains unchanged or increases slightly. Tungsten alloys may therefore be preferable to unalloyed tantalum in applications that demand substantial ductility at high rates of strain. We briefly discuss possible mechanisms for plastic flow in tantalum and how they might be affected by tungsten additions to produce the effects we observe.

Book Synopsis Research and Development of Tantalum- and Tungsten-base Alloys by : A. L. FEILD JR
Download or read book Research and Development of Tantalum- and Tungsten-base Alloys written by A. L. FEILD JR and published by . This book was released on 1961 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of alloying upon the properties of Ta and W were examined. A 20-g button survey was made of the Ta-W-Hf and Ta-W-Re ternary systems to determine hardness, fabricability, oxidation resistance, and microstructure as a function of composition. The effects of substituting or adding Ti, Zr, V, Cb and Cr into Ta- and W-base alloys were also examined. A satisfactory technique was worked out for melting and fabrication of Ta-base alloys by arc melting from pressed and sintered electrodes and impact extruding at 1700 C with a Dynapak machine. The mechanical properties of the Ta-base alloys were determined from -320 F to 3000 F on 50 mil sheet specimens. The alloys in general possess a remarkable combination of excellent low temperature ductility and substantial high temperature strength.
