摘要

Mg_2Co- and MgCo_2-like local atomic arrangements in mechanically alloyed Mg_xCo_(100-x) were investigated using atomic pair distribution function (PDF) analysis derived from synchrotron X-ray total scattering data. We show that changes in Mg_xCo_(100-x) PDFs with x are well explained by the structural features of Mg_2Co and MgCo_2. This strongly supports our two-phase model picture where Mg_2Co-like phase continuously increases while MgCo_2decreases with increasing Mg content in Mg_xCo_(100-x).
