| Abstract Scope |
Multi-material additive manufacturing(MMAM) has significantly enhanced the functionality of additive manufacturing(AM) by enabling the seamless integration of dissimilar alloys. MMAM combines AM advantages, including design flexibility, material efficiency, and rapid production, with the ability to tailor mechanical properties through spatial material distribution. MMAM processes are broadly categorized into (I) Bimetallic – direct transition between material composition; (II) Functionally graded material(FGM) – gradual transition.
This research focuses on the mechanical response of bimetallic IN625 and SS316 fabricated via selective powder deposition MMAM. Nine deposition strategies (vertical, diagonal, alternating, etc.) and two deposition sequences are investigated. ASTM E8 standard subsize specimens are experimentally tested under uniaxial tensile test loading. Defects along the transition zone are characterized using x-ray CT, and localized strain is analyzed through DIC. The findings will accelerate MMAM adoption in applications across energy, aerospace, biomedical, and defense, where tailored material properties are critical for next-generation engineering solutions. |
