    • In Situ Thermography During Laser Powder Bed Fusion of a Nickel Superalloy 625 Artifact with Various Overhangs and Supports

    Metadata Updated: July 29, 2022

    This document provides details on the experiment and associated measurement files available for download in the dataset ?In Situ Thermography During Laser Powder Bed Fusion of a Nickel Superalloy 625 Artifact with Various Overhangs and Supports.? The measurements were acquired during the fabrication of a small nickel superalloy 625 (IN625) artifact using a commercial laser powder bed fusion (LPBF) system. The artifact consists of two half-arch features with increasing degrees of overhangs, from 5° to 85°, in increments of 10°. The artifact geometry and process are controlled to ensure consistent processing along the overhang geometry, thus enabling the effect due to overhang geometry and support structures to be isolated from effects due to inter-layer scan-strategy variations that are typical in commercial LPBF processes. The measurements include high-speed thermography of each layer, from which radiant temperature, cooling rate, and melt pool length are calculated. The objective of this experiment and data dissemination is twofold. First, to provide data for the modeling community for model validation to ensure that their models are accurately accounting for the effect of overhang geometries and support structures in thermal models. The second objective is to provide fundamental insight into these effects for researchers and process designers.
