Abstract (en)
[origin: US2018016668A1] Described is α-TiAl alloy which, besides titanium, comprises 42 to 48 at. % aluminum, 3 to 5 at. % niobium, 0.05 to 1 at. % molybdenum, 0.2 to 2.2 at. % silicon, 0.2 to 0.4 at. % carbon, 0.05 to 0.2 at. % boron, and optionally tungsten, zirconium and hafnium, as well as unavoidable impurities, and at room temperature has a microstructure which comprises globular colonies of lamellae of α2-Ti3Al and γ-TiAl, as well as silicide precipitates, and essentially no β phase. A method for producing a component made of this alloy is also described.
