ABSTRACT:
Diffusion bonding of aluminum alloy objects of different sizes and shapes may be greatly improved when the surface of the object is exposed to a mechanical deformation cycle which forms a cold-worked surface microstructure, followed by a heat treatment cycle to produce recrystallization of the surface layer. The method of the invention results in the formation of finer grains at the surface which enhances the strength of a diffusion bond.
