Structural and thermal properties of Cu-Hf-Ti ternary metallic glasses

Cu-Hf-Ti ternary metallic alloys were prepared by melt spinning. The thermal stability of the alloys with various Ti contents was studied by differential scanning calorimetry. The evolution of short range order with annealing treatment was also investigated by means of perturbed angular correlation. The results for the initial as-spun alloys indicate that the short range order can be described by a dense packing of atoms. The variation of electric field gradient with alloy composition is comparable to that previously observed in binary and multi-component Zr- and Hf-based amorphous alloys.
