Abstract: The present disclosure relates to reactive manufacturing methods to disperse fine second phase particles within a matrix, and compositions made thereof. Specifically, the reactive manufacturing methods are based on in-situ reaction synthesis during an additive manufacturing (AM) process to fabricate composite components for structural and/or functional applications. The composite components can be particularly useful in oil and gas applications.

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.
