Microstructure and Physical Properties of Nonmagnesium and Magnesium-Based High-Entropy Alloys: A Comparison Study

CODEN: MPCACD

Abstract

In this investigation, (Ti-Mo-Zr)60Co20Cr20, (Ti-Mo-Zr)60Al30Si10 (non-magnesium-based), and (Ti-Mo-Zr)60Cu10Mg30 (magnesium-based) high-entropy alloy (HEA) samples are prepared via mechanical milling and then by spark plasma sintering technique. The microstructure morphology is examined using x-ray diffraction and scanning electron microscopy with energy-dispersive x-ray spectroscopy. The microstructure reveals that there would be a strong correlation between phase structure and sustainability for localized corrosion behavior. The lowest crystallite size of the magnesium-based HEA powder mixture suggests the highest corrosion resistance because of the solid-solution face-centered cubic and body-centered cubic phases for 20 h of milling. The correlation between the microstructural morphology and functional properties such as hardness, corrosion resistance, and potentiodynamic parameters are compared for both magnesium-based and non-magnesium-based HEAs and analyzed to elucidate their suitability for lightweight vehicle applications.
