    • Thermographic measurements of single and multiple scan tracks on nickel alloy 625 substrates with and without a powder layer in a commercial laser powder bed fusion process (an additive manufacturing technology)

    Metadata Updated: September 30, 2025

    This dataset contains thermographic measurements acquired during single and multiple track scans on bare substrates and on single layers of powder. The substrates and powder are nickel alloy 625 and the experiments are performed inside a commercial laser powder bed fusion machine. There are four experiment cases: 1) a single scan track on a bare substrate, 2) a single scan track on a single hand-spread layer of powder, 3) multiple (39) scan tracks covering an area on a bare substrate, and 4) multiple (39) scan tracks solidifying a single hand-spread layer of powder. Thermographic measurements are performed using a camera system sensitive to wavelengths between 1350 nm and 1600 nm. The camera acquires frames with an integration time of 0.04 ms and a frame rate of 1800 frames per s. The camera signal and radiant temperature values based on a black body calibration are provided. True temperature is not provided because emissivity of the surfaces is unknown. This data was used to measure melt pool length and cooling rate based on radiant temperature as part of the work in: Heigel, J. C. & Lane, B. (2017). "The effect of powder on cooling rate and melt pool length measurements using in situ thermographic techniques." In Proceedings of the 2017 Annual International SFF Symposium (https://www.nist.gov/publications/effect-powder-cooling-rate-and-melt-pool-length-measurements-using-situ-thermographic)
