Additive manufacturing of Inconel 718 – Ti6Al4V bimetallic structures

Bimetallic structures belong to a class of multi-material structures, and they potentially offer unique solutions to many engineering problems. In this work, bimetallic structures of Inconel 718 and Ti6Al4V (Ti64) alloys were processed using laser engineered net shaping (LENS™). During LENS™ processing, three build strategies were attempted: direct deposition, compositional gradation and use of an intermediate bond layer. Inconel 718 and Ti64...
