METHOD OF MANUFACTURE (VERSIONS) OF THE DETAILS OR THE SEMI-FINISHED PRODUCTS, WHICH CONTAIN THE INTERMETALLIC TITANIUM-ALUMINIDE ALLOYS AND ALSO THE DETAIL MANUFACTURED BY THE METHOD Russian patent published in 2007 - IPC B32B15/01 

FIELD: mechanical engineering; method of manufacture (versions) of the details or semi-finished products containing the intermetallic titanium-aluminide alloys.

SUBSTANCE: the invention is used for manufacture of the rotor disks or the vanes of the turbines to the set of the laminated bodies made out of one or several titanium-aluminide alloys add the coarse outlines with production of the having the enlarged dimensions preform with the geometry of the being manufactured detail or the semi-finished product, then join them to each other for formation of the common body and shape the desirable final form of the common body. The joining and shaping of the final form is exercised within one work operation. Adding of the coarse outlines to the laminated bodies is exercised by the pressure shaping or cutting. Joining of the stockpiled laminated bodies is exercised by the diffusion welding or by the soldering, and the shaping of the final form of the common body is exercised by the forging of the common body. At that the indicated operations may be conducted in the vacuum environment or in the atmosphere of the inert gases. The laminated bodies forming the common body consist of the various titanium-aluminide alloys have the different microstructure and the texture. Orientation of the surfaces of the stockpiled laminated bodies is set concerning the orientation of the direction of the basic loading of the generated final form. The invention allows to manufacture of the products capable to withstand the great loading, possessing the high geometrical stretching and the thermal stability.

EFFECT: the invention ensures manufacture of the products capable to withstand the great loading, possessing the high geometrical stretching and the thermal stability.
