Abstract

The effects of alloying on mechanical properties of tantalum have been studied. Both dispersion-strengthened and solid-solution strengthened tantalum alloys exhibit high-strength at elevated temperatures while maintaining good fabricability and excellent low-temperature ductility. Strength data to 1650 C (3000 F) are reported. The oxidation resistance of tantalum can be improved severalfold by alloying. Several alloying elements were found effective in reducing scaling and contamination up to 1400 C (2550 F). References are included.
