摘要： An apparatus for producing a circular metal article reinforced by fibres in selected parts of its cross-section is described in which a metal blank of the article is formed and provided with at least one annular groove opening in the axial direction, preforms of reinforcing fibre and filler metal are placed in the groove which is then closed by a metal plug, and the assembly is isothermally forged to produce the article in a single forging step which serves to compress the preforms, weld the assembly together, and shape the article. Such articles may be used for machining high performance rotors for turbojet engines.

摘要： A process for constructing a circular metallic article which includes a hub and a plurality of vanes mounted on the periphery of the hub wherein the vanes are placed in position around the hub, formers are arranged between the blade portions of the vanes, a dimensionally stable belt having a low thermal expansion coefficient is placed circumferentially around the vanes and the formers, and the assembly is subjected to an isostatic compression at the isothermal forging temperature and pressure of the materials of the hub and the vanes such that the vanes are diffusion welded to the hub and the blade portions of the vanes are compressed to shape.
