  • Friction welding of .gamma. titanium aluminide to steel body with nickel alloy connecting piece there between
    Patent number: 5431752
    Abstract: The component comprises a body (5) composed of an alloy based on a .gamma.-titanium aluminide, a steel body (2) and a connecting piece (4) composed of a nickel-base alloy. The .gamma.-titanium aluminide body (5) and the steel body (2) are rigidly joined together by means of the connecting piece (4). The joint between the .gamma.-titanium aluminide body (5) and the connecting piece (4) is produced by friction welding. The nickel-base alloy has a nickel content of less than 65 percent by weight. This achieves the result that the friction-welding joint of the .gamma.-titanium aluminide body (5) to the connecting piece (4) can be produced at comparatively low temperatures. During the friction welding, the risk of crack formations in the embrittlement-prone .gamma.-titanium aluminide body (5) is therefore appreciably reduced.
