Abstract (en)
[origin: EP0924308A1] A titanium-aluminum-niobium intermetallic phase alloy, which contains molybdenum, silicon, tantalum and/or zirconium and which has the composition given below, is new. A titanium based intermetallic phase alloy has the composition 16-26 at.% Al, 18-28 at.% Nb, 0-2 at.% Mo, 0-0.8 at.% Si, 0-2 at.% Ta, 0-2 at.% Zr and balance Ti, the sum of Mo + Si + Zr + Ta being greater than 0.4 at.%.
