Worldwide, there are emerging interests in advanced manufacturing of multi-material structures (e.g., by additive manufacturing), for a wide range of applications for the purpose of optimized balance of quality, weight, cost, productivity, etc. For instance, a rocket/jet engine or gas turbine contains structural materials ranging from aluminum alloys, high strength steels, titanium alloys, nickel-base superalloys, to composite materials, depending primarily on the operation temperature of each part. Engineered vehicle structures also contain various grades of steels, aluminum and magnesium alloys, depending on the needs for performance, safety and cost. challenges exist in joining these similar and dissimilar materials due to the mismatches in thermal physical properties and chemical incompatibility. This project aims to design multi-principal-element alloys (MPEAs) that can serve as a diffusion barrier and ductile interlayer to enable joining of incompatible materials.
