ABSTRACT:
A method for joining a first metal surface to a second metal surface that includes providing powder metal particles substantially all of which have hardnesses lower than the hardnesses of the first and second metal surfaces, at normal temperatures; locating the particles in a layer between the first and second metallic surfaces, to form an assembly; heating the assembly to an elevated temperature or temperatures below the softening temperature of the first and second metallic surfaces; and effecting compression of the layer by and between the first and second surfaces at a pressure level or levels below the compressive yield strengths of the first and second surfaces, and above the compressive yield strengths of the particles, and for a time duration to effect a bond between the first and second metallic surfaces.
