The mechanical properties of ternary W-Nb-C, W-Ta-C, and W-Zr-C alloys are investigated and compared to those of binary W-Nb, W-Ta, and W-Zr alloys at temperatures in the range 300 to 600/sup 0/C and 1500 to 2000/sup 0/C. Major conclusions are that alloying of W and W-C alloys with additions of Zr, Nb, and Ta increases stress- and creep-rupture strengths, that the alloying elements raise the ductile-brittle transition temperature of W and W-C alloys, and that at low temperatures the most effective alloying elements are carbon and group IV elements.
