To fabricate and evaluate a crack-free steel-copper functionally graded material using twin-wire and arc additive manufacturing.
Deposited a copper-based alloy onto high-strength low-alloy steel using twin-wire and arc additive manufacturing (T-WAAM).
Characterized microstructure, phase evolution, and interfaces using optical microscopy, scanning electron microscopy, and high-energy synchrotron X-ray diffraction.
Evaluated gradient properties through hardness mapping, electrical conductivity testing, and tensile testing.
Detected retained δ-ferrite in a copper matrix across the interface region resulting from compositional mixing.
Achieved a smooth gradient in both hardness and electrical conductivity along the build height of the component.
Demonstrated an ultimate tensile strength of 690 MPa and an elongation at fracture of 16.6% in the fabricated part.
