Reverse Monte Carlo simulations of an amorphous Cr25Nb75 alloy produced by mechanical alloying

The local atomic structure of an amorphous Cr25Nb75 alloy produced by mechanical alloying was determined using only one X-ray total structure factor S(K) as input data for reverse Monte Carlo simulations. The results showed that the amorphous alloy has a local atomic structure similar to that predicted by the additive hard sphere model for a Cr and Nb mixture with same composition of the alloy, and quite different of those found in the cubic and hexagonal Cr2Nb crystals.
