INVESTIGATION OF THE PROPERTIES OF TANTALUM AND ITS ALLOYS

Abstract

Effects of alloying on mechanical properties of Ta were studied. Both dispersion-strengthened and solid-solution strengthened Ta 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 Ta can be improved several fold by alloying. Several alloying elements were found effective in reducing scaling and contamination up to 1400 C (2550 F).
