Evidence for a reversible structural transformation in the metallic glassCo58Ni10Fe5B16Si11

Resistivity measurements and calorimetric data are presented for the metallic galss ${\mathrm{Co}}_{58}$ ${\mathrm{Ni}}_{10}$ ${\mathrm{Fe}}_5$ ${\mathrm{B}}_{16}$ ${\mathrm{Si}}_{11}$. The results show a reversible transition in the temperature dependence of the resistivity and a small endothermic peak in the differential scanning calorimetry traces at a well-defined temperature. These effects are attributed to a reversible structural transformation in the metallic glass.
