ABSTRACT:
Diffusion bonding of aluminum alloy objects of different sizes and shapes are greatly improved when the surface of the object is exposed to a high energy source which causes a heat treatment or melting and rapid quenching or solidification at the surface. Such treatment results in the formation of finer grains at the surface which enhances the strength of a diffusion bond.
