Fatigue crack growth in IN718/316L multi-materials layered structures fabricated by laser powder bed fusion
Fatigue crack growth in IN718/316L multi-materials layered structures fabricated by laser powder bed fusion
Multi-materials additive manufacturing (MMAM) allows the functional optimisation of components by tailoring the addition of alloys at different design locations in a single operation. In this study Laser Powder Bed Fusion (L- PBF) technique was used to manufacture layered specimens combining IN718 and 316L materials. The micro-structure and mechanical properties were studied by scanning electron microscopy (SEM), tensile, micro and nanohardness testing. The fatigue tests were performed to determine the crack propagation process through multi-layer specimens in the as-built (AB) state.

Abstract
Multi-materials additive manufacturing (MMAM) allows the functional optimisation of components by tailoring the addition of alloys at different design locations in a single operation. In this study Laser Powder Bed Fusion (L- PBF) technique was used to manufacture layered specimens combining IN718 and 316L materials. The micro-structure and mechanical properties were studied by scanning electron microscopy (SEM), tensile, micro and nanohardness testing. The fatigue tests were performed to determine the crack propagation process through multi-layer specimens in the as-built (AB) state.
