Abstract Scope |
This research elucidates the relationships between critical process parameters and resultant microstructures and tensile strength for the deposition of nickel-base alloys upon low-alloy steel parts using powder-based directed energy deposition (DED). Deposition of nickel-based alloys have shown success in mitigating brittle phase formation in iron-carbon heat-affected zones under specific thermal conditions. Correlating in-situ geometric and thermal data to resultant microstructural outcomes remains difficult. Thus, this research explains relationships between DED processing parameters (laser power, scanning speed, powder mass flow rate) and the resultant properties of the remanufactured alloy, i.e., microstructural characteristics and tensile strength. Simultaneously combining in-situ structure light scanning with thermal imaging allows for correlating the thermal profile of depositions with laser parameters. Initial work points toward a correlation between in-situ and geometrical sensing and grain size outcomes. This study aims to develop intelligent DED processes for the remanufacturing industry by employing in-situ signals to better understand process outcomes. |
