Abstract (en)
[origin: US2004045644A1] The invention relates to a component produced in one piece from an intermetallic gamma-TiAl-based alloy with graduated microstructure transition between spatially adjacent areas each of different microstructure structure, which has a lamellar cast microstructure composed of alpha2/gamma lamellae in at least one area, and a near-gamma microstructure, duplex microstructure or fine-lamellar microstructure in at least one other area, and a transition zone with graduated microstructure, in which the lamellar cast microstructure gradually changes into the other named microstructure, is present between these areas, as well as to a process for its production.
