Formation of two-dimensional AlCu alloy from the liquid state is studied by molecular dynamics simulations. Model contains 10000 atoms (5000 Al atoms and 5000 Cu ones). Freezing temperature is found which has a reasonable value. Structure is studied via radial distribution functions, coordination number and interatomic distance distributions, ring statistics etc. We find that 2D-AlCu alloy has a triangle lattice structure the bond-length of which has a reasonable value compared to that of 3D counterpart. In addition, due to weak Al-Al and Cu-Cu interactions compared to Al-Cu one there is no phase separation in the alloy. Various defects are defined and discussed.
