Formation of the short-range order in Al-based liquid alloys

The short-range order in binary and ternary liquid alloys of aluminum with 3d-transition metals (TM) was studied by the X-ray diffraction method and Reverse Monte Carlo simulations. The causes of the presence of the prepeak and asymmetric shape of the second peak on the experimental total structure factors were discussed. The effect of the transition metal atom type on the short-range order of Al-based liquid alloys was demonstrated.

► The strength of the interatomic interaction and sizes of atoms as factors of formation of the SRO in liquid alloys
► Investigation of the SRO of the Al-based liquid alloys
► The influence of transition metal additives on the CSRO and the non-crystalline packing
