It is shown that the quality joints of CM 1013 and 1501 with 4 % C can be obtained in using an aluminium ductile interlayer. Optimum conditions of diffusion bonding in vacuum are given. Strength of joints of CM 1501 + 4 % C reaches 443.8 MPa, while that of CM 1013 + 4 % C joints is 295 MPa.
Keywords: diffusion bonding, dispersion strengthened composite, weldability, aluminium interlayer, thermodeformational cycling, structure, strength, hardness
