Description
These measurements were performed as part of the 2018 Additive Manufacturing Benchmark Test Series (AM-Bench), specifically supporting the melt pool geometry challenge (CHAL-AMB2018-02-MP) and cooling rate challenge (CHAL-AMB2018-02-CR). This dataset and the associated experiments are part of a continuing series of controlled benchmark tests, in conjunction with a conference series, with two initial goals, 1) to allow modelers of Additive Manufacturing processes to test their simulations against rigorous, highly controlled additive manufacturing benchmark test data, and 2) to encourage additive manufacturing practitioners to develop novel mitigation strategies for challenging build scenarios. More information regarding the AMBench 2018 study can be found at www.nist.gov/ambench. Multiple laser scan tracks were performed on bare nickel-based superalloy IN625 substrates using three different combinations of laser power and scan speed. A high-speed infrared camera was used to measure the infrared emissions during each scan track, allowing measurement of the melt pool length and cooling rate of the solidified material. Details related to this dataset are provided in the associated NIST Journal of Research article (in press). The associated publication with experiment details and ex-situ characterization is Lane et. al. 2020 (https://doi.org/10.1007/s40192-020-00169-1).For dataset description article; refer to https://doi.org/10.6028/NIST.AMS.100-53
