Effect of Zr Additions on Phase Transformations, Microstructure and Wear Resistance of High-Entropy AlCoCrCuFe Alloy

  • Published:
Metal Science and Heat Treatment Aims and scope

Effect of zirconium additions on the microstructure, phase composition, microhardness and wear resistance of high-entropy AlCoCrCuFe alloys with equal mole fractions of the components is studied. The methods of x-ray diffraction, optical and electron microscopy and mechanical wear tests are used for the metallographic study. Zirconium additions are shown to affect positively the hardness, strength and wear resistance of the AlCoCrCuFeZr alloy due to refinement of grains, solid-solution hardening and changes in the phase composition.
