Patent ID: 8075713

Claim:
A method for production of precision castings by centrifugal casting, comprising: a) providing in a crucible a titanium alloy melt of the following composition: Ti 45-52 at. % Al 45-50 at. % X1 1-3 at. % X2 2-4 at. % X3 0-1 at. % , where X1=Cr, Mn, V, X2=Nb, Ta, W, Mo, X3=Si, B, C; b) forcing the titanium alloy melt by means of centrifugal forces from the crucible into a mold; c) solidifying the titanium alloy melt within the mold thereby creating a titanium alloy casting having a lamellar microstructure; and d) reheating the titanium alloy casting for a duration of 80 to 150 hours at a temperature higher than the eutectic temperature and lower than the alpha-transus temperature of the titanium alloy casting.
