Title: Additive manufactured interpenetrating phase composite

Abstract

A method for preparing metal/metal interpenetrating phase composites is provided. The method includes forming a preform using additive manufacturing. The preform defines a materially continuous three-dimensional open-cell mesh structure. The preform includes a first metal having a melting point. The method further includes pre-heating the preform to a first temperature less than the melting point of the first metal. The method includes infiltrating the preform with a second metal in liquid form. The second metal has a melting point lower than the melting point of the first metal. The method also includes allowing the second metal to cool and form a solid matrix. The solid matrix defines a continuous material network.
