Abstract
A process for additive manufacture of an article including conjoined first and second metals, wherein the first metal includes one of steel and titanium and the second metal includes another of the steel and the titanium. The process comprises arranging an interface layer of a third metal on a substrate of the first metal, wherein the third metal is capable of forming an alloy with the first metal and capable of forming an alloy with the second metal. The process further comprises supplying a consumable form of the second metal to a locus of the interface layer and heating the locus of the interface layer in an non-reactive environment. In this process, the heating fuses the consumable form of the second metal to render a fused form of the second metal and joins the fused form of the second metal to the interface layer.
