In situ pyrometry reveals sharp drop in Inconel 625 absorptivity during powder bed fusion

Researchers at the University of Texas at El Paso, working with Sandia National Laboratories and FAR Associates, have developed a method to approximate the absorptivity of Inconel 625 during powder bed fusion by analyzing in situ radiation thermometry data collected during electron beam powder bed fusion (PBF-EB/M). Reported in Additive Manufacturing Letters, the study shows […]
