| Abstract Scope |
Al0.1CoCrFeNi alloy is an attractive high-entropy alloy (HEA) with its excellent corrosion resistance and attractive mechanical properties. As the mass-production process of this HEA has not been established yet, low-volume and high-valued processes, e.g., laser powder bed fusion (LPBF), are preferred to produce Al0.1CoCrFeNi products. In an effort to produce high-quality Al0.1CoCrFeNi powders for LPBF, the gas-atomization method was used under argon (or nitrogen) atmosphere. The powder characteristics fabricated by gas atomization are carefully investigated in this study. A powder size determinator was used to assess the powder size distribution, and the powder morphology was characterized, using scanning electron microscope (SEM). Additional compositional analyses employing energy-dispersive x-ray spectroscopy, oxygen/nitrogen determinator were conducted to detect unfavorable impurities like oxygen or to check the composition homogeneity of powders. |
