ABSTRACT:
Two component workpieces (1, 3) consisting of different superalloys or of the same superalloy are bonded together to form a monolithic whole, with the insertion of a layer 1-2 mm thick consisting of a powder (4) of composition similar to or identical to that of the component workpieces (1, 3), by hot pressing in accordance with the diffusion bonding process. The workpiece surfaces to be bonded do not have to have narrow tolerances, but are with advantage provided with grooves (5). The groove depth (s) may be 0.25 mm. Pressing temperature =950.degree.-1,000.degree. C., deformation velocity .epsilon.=1-5.10.sup.-1 s.sup.-1, degree of deformation .epsilon.=0.1-0.02. The process is suitable for the bonding together of component workpieces (1) consisting of a dispersion-hardened, nickel-based superalloy or of component workpieces (1) of such an alloy and workpieces (3) consisting of a cast conventional superalloy.
