Microstructural characterization and mechanical properties of high entropy MnNiCuAl alloys
Abstract
In this work, the fabrication of a multicomponent high entropy MnNiCuAl alloy. The calculated characteristic parameters such as, enthalpy, atomic difference, and Ω confirmed a high entropy MnNiCuAl alloy showing two phases bcc and fcc. MnNiCuAl alloy was fabricated by melting of pure elements with an electric-arc furnace. The high entropy alloy was characterized by optical microscope, scanning electron microscope, X-ray diffraction and Vickers hardness. The microstructure of alloy revealed the presence of two phases, dendritic and interdendritic, which confirmed the X-ray diffraction results and the Thermo-Calc calculation. The hardness was determined to be about 359 VHN.
