Abstract: Methods disclosed herein include using additive manufacturing to create a joint between a first metallic material and a second metallic material that is different from the first metallic material, wherein the porosity of the joint is less than about 0.1 percent by volume measured according to ASTM B-962. The additive manufacturing can be performed such that no intermetallic brittle phase forms between the first metallic material and the second metallic material.
