Abstrakt: In this paper, the possibility of producing a bimetallic disc-shaft-type part for a gas turbine engine made from dissimilar heat-resistant nickel-based superalloys by means of pressure welding in the presence of shear deformation is considered on the basis of computer simulation. It is shown that the quality of a solid-phase joint of the part depends on the scheme of shaft insertion into the disk, the angle of the shaft taper and the degree of surface treatment.
