摘要

•Laser-powder bed fusion (L-PBF) fabrication of functionally graded nickel-titanium (NiTi)-AISI 316L material demonstrated.•Excellent bonding between NiTi and AISI 316L alloys controlled via complex bands of multi-material layers.•Phase and microstructural evolution controlled through the L-PBF settings.•Multi-material phase and microstructure formation/evolution mechanisms elucidated.
