Titanium-Niobium-Base Ternary Transition-Metal Alloys (Except Titanium-Zirconium-Niobium)

Abstract

This discussion of ternary Ti-Nb-base transition metal alloys commences with Ti-Hf-Nb — Hf, being a group-IV element may, like Zr, be regarded as a substitute for Ti — and continues with the two Ti-Nb-(group-V)TM alloys Ti-Nb-V, and Ti-Nb-Ta, in which the third solute may be regarded as substituting for Nb. In recent years Ti-Nb-Ta has been shown to be a very important system both economically and technically; accordingly, its properties have been given special emphasis in this review. The chapter concludes with a survey of the superconducting properties of ternary alloys of Ti-Nb with the group-VI elements Cr, Mo, and W, the group-VII elements Mn and Re, and with several members of group VIII of the periodic table.
