Fatigue crack growth in IN718/316L multi-materials layered structures fabricated by laser powder bed fusion
Source abstract
Abstract
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 microstructure 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.
