ABSTRACT:
Novel Ti-Al-Nb-Cr alloys incorporating in their microstructure the hexagonal DO.sub.19 phase, the omega-type B8.sub.2 phase, the cubic B2 phase, and, optionally, the orthorhombic O phase. The intermetallic alloys consist essentially of, in atomic percent, about 48-62% Ti, about 28-32% Al, and about 10-20% Nb with Cr, wherein Cr is preferably present at about 4-16% of the total concentration.
