"transition allloys: Inconel 718 (lightweight high strength nickel-based) and C103 (high temperature resistant niobium-based) powders... using blown-powder directed energy deposition beam machine and changing rate at which powders flow, inert argon environment, change composition of joined metals so that cracks not created... rocket engines, aerospace manufacturing, fusion and fission reactor fabrication, marine-related, renewable energy, high-strength superalloys and refractory alloys for extreme environment, weld-free"
