The freezingmechanism, recently suggested for amonodisperse hard-disk fluid [Huerta et al, Phys. Rev. E, 2006, 74, 061106] is extended here to an equimolar binary hard-disk mixtures. We are showing that for diameter ratios, smaller than 1.15 the global orientational order parameter of the binarymixture behaves like in the case of amonodisperse fluid. Namely, by increasing the disk number density there is a tendency to forma crystallinelike phase. However, for diameter ratios larger than 1.15 the binary mixtures behave like a disordered fluid. We use some of the structural and thermodynamic properties to compare and discuss the behavior as a function of diameter ratio and packing fraction. [ABSTRACT FROM AUTHOR]
