This work presents an integrated directed energy deposition (DED) approach utilizing a multi-powder feeder with real-time continuously variable composition functionality, mixer and nozzle to fabricate Ti-Ni-Nb gradient alloys controlled compositional variations. The high-throughput methodology enables rapid alloy design optimization by allowing precise manipulation of chemical phase structures within single deposited track. EDS analysis confirms gradual increase in titanium content, nearly constant nickel content decrease niobium along the scanning path, aligning expected powder-feeding trends. X-ray diffraction (XRD) further reveals transition from niobium-rich intermetallic compounds (NbNi4, Nb8Ni) at beginning titanium-rich phases (Ti, Ti2Ni) end, demonstrating ability tailor distributions through control. integrating theoretical predictions experimental screening. study establishes novel framework for discovery functionally graded materials, paving way advanced applications aerospace, biomedical implants high-performance structural components.
