The aim of this work is to analyze the morphology and composition of iron-aluminide (FeAl) powders produced by liquid metal atomization using a de Laval nozzle. The variables studied are atomization gas pressure and melt nozzle diameter. Different sized powders were characterized via SEM, XRD, and EDS analysis and were found to be similar in composition and shape (spherical) regardless of their size. The paper provides a detailed description of how the powders were produced, classified, and tested, and presents and interprets the results.
