摘要: Al0.4FeCrNiCox (x = 0, 0.25, 0.5, 1.0 mol) high-entropy alloys are developed by arc melting route to investigate the effect of cobalt content on thermal, mechanical, and microstructural properties. The phase, microstructure, chemical composition analyzed using x-ray diffraction, transmission electron microscope, scanning microscope with attached energy-dispersive spectrometer. obtained results have shown that (x = 0-0.5 mol) form a simple FCC + BCC-type solid solution Al0.4FeCrNiCox=1 HEA forms single-phase FCC structure. compressive yield strength, microhardness, thermal conductivity observed decrease from 965.22 233.37 MPa, 253.6 155.6 HV, 4.87 2.674 W/mK, respectively, whereas electrical resistivity is increase 150.30 273.74 µΩ-cm addition x = 0-1 mol. Differential calorimetry analysis has indicated thermally stable up 1000 °C.
