Abstract
An overview of the additive/subtractive hybrid manufacturing (ASHM) research on three heat resisting materials – 18Ni-300 maraging steel, 316L stainless steel, and Inconel 718 (hereinafter 18Ni-300, 316L and IN718) – is provided to bridge key knowledge gaps and establish the respective process-microstructure-property relationships. The results examine validating the final surface roughness properties in the as-built and machined conditions in terms of the linear and areal parameters. Microscopic observations are also detailed to identify the influence of dry machining intermittent passes and/or laser conditions on microstructural features, as well as the bulk density. Mechanical stability assessment involved hardness measurement and tensile testing to evaluate the mechanical response of the materials built by in-envelope ASHM.
