Two new quaternary CrxTi0.75Mo0.75V1.5−xAlC2 (x = 1.25 and 1) MAXs and Cr0.75Ti0.75Mo0.75V0.75AlC2 are synthesized via hot pressing. An unprecedented transition in M-site atomic occupancy from out-of-plane order to solid solution is observed along with composition variation, which also increases the configurational entropy from medium- to high-entropy. Through experimental observations and theoretical calculations, the influence of the atomic distribution on the material properties is analyzed. Eventually, an approximately 40% increase in the Vickers hardness compared with that of Cr2TiAlC2 and a low thermal conductivity are detected for the three MAXs, which can be attributed to the solid solution strengthening effects and the enhanced scattering of both electrons and phonons from the high-entropy structure.
