Refractory metals in the Space Age
Growth in the utilization of refractory metals (Zr, Hf, V, Nb, Ta, Cr, Mo, w, Re, Ru, Os, Rh, Ir) has seen a steady but measured increase in recent years because of their special properties. Their high melting points and concomitant high temperature strengths allow for such things as higher thermodynamic efficiencies in heat engine designs, but other properties such as practical superconductivity at reasonable temperatures and resistance to highly corrosive chemicals are probably being utilized more in today's applications. Current applications range from the use of niobium-base alloys in superconducting magnets to the use of zirconium containment vessels for corrosive chemicals. Recently developed applications of refractory metals are surveyed in relation to their unique properties, and some plans for their utilization in future space applications are discussed. new innovations in alloy composition and fabrication that have opened doors to new applications of the refractory metals are also discussed.
