摘要：

In this study AlxCrFeCoNi (x, values of molar ratio, x = 1.0, 0.8 and 0.6) were prepared using a vacuum arc melting method. The aluminium addition on the microstructures, hardness and tenacity for these high entropy alloys were investigated. AlxCrFeCoNi microstructures present well defined dendrites and interdendrite spaces with polyhedral compounxds and precipitates in the vicinity of the grain boundary. The eutectics obtained are very fine and homogeneously dispersed within the matrix when x = 1.0 and segregations appear due to chromium grain refining effect and decrease of aluminium content (x = 0.8 and 0.6). As aluminium content decreases the hardness decreases dramatically, with 55% and the tenacity was improved with approximately 7.7%.
