Abstract The effect of entropy on the strengths of the disordered and ordered phases was investigated. Cost effective AlCoxCrFeNi (x = 0, 0.25, 0.5, 0.75, and 1) high-entropy alloys were fabricated reducing Co content. The strength was considerably reduced when the Co content was zero. This was attributed to the low hardness of the A2 phase due to reduced configurational entropy compared with quinary system. On the other hand, the ordered B2 phase showed the opposite tendency. This result shows that the configurational entropy causes opposing effects on disordered and ordered phases, and the importance of considering the effect of entropy on each phase when the number of elements changed, and an alloy is composed of two or more phases, in particular, having BCC structure. Highlights Effect of Entropy on the mechanical properties of each phase was studied. Considerably lower YS of the AlCrFeNi HEA is due to the low strength of the A2 matrix. Configurational entropy causes opposing effects on disordered and ordered phases.
