Abstract
A method, article of manufacture, and system for joining different materials is described. In a principal embodiment, two articles, for example different metals, are placed in proximity to one another with an interfacial area. One article is heated using a laser that is scanned across from a point remote from the interface to a point at or just short of the interface. In embodiments, the interfacial bond region is characterized by a homogenous mixed phase region with very low to substantially no brittle intermetallics.
