摘要

The atomic structure of an amorphous Si24Nb76 alloy produced by mechanical alloying was investigated by using one X-ray total structure factor S(K) as input data for reverse Monte Carlo (RMC) simulations. The partial SSi-Si(K). SSi-Nb(K). SNb-Nb(K) structure factors and G(Si-Si)(r), G(Si-Nb)(r), G(Nb-Nb)(r) pair probability functions were obtained from the RMC simulations. The structural parameters (interatomic distances and co-ordination numbers) for the first neighbors were extracted and compared with those found in the Nb3Si compound. It was observed some resemblance between these phases.
