RETRACTED: A Novel Al0.5CuFeNiV High Entropy Alloy: Phase Analysis, Microstructure and Compressive Properties (Retracted article. See vol. 62, pg. 1428, 2021)

The phase component, microstructure and compressive properties of a novel high entropy alloy, Al0.5CuFeNiV in as-cast and annealed conditions were investigated. Its phase structure is composed of FCC+B2 (ordered BCC) phase in both states. The ordered BCC phase is the major dendritic phase depleted with Cu, while the FCC phase is enriched with Cu, forming a netlike framework. Moreover, the alloys in both states possess a promising trade-off in strength and ductility. Specifically, the yield strength and the elongation of the as-cast alloy are 1456MPa and 10.0%, respectively. After annealing, the strength decreases to 861 MPa, while the elongation increases to 15.5%. The combination of phase constitution, microstructure morphology, and solid solution strengthening was conducted to explain their mechanical behavior.
