Abstract
Mg2Co- and MgCo2-like local atomic arrangements in mechanically alloyed MgxCo100–x were investigated using atomic pair distribution function (PDF) analysis derived from synchrotron X-ray total scattering data. We show that changes in MgxCo100–x PDFs with x are well explained by the structural features of Mg2Co and MgCo2. This strongly supports our two-phase model picture where Mg2Co-like phase continuously increases while MgCo2 decreases with increasing Mg content in MgxCo100–x.
