Abstract
The effects of microalloying of Ti and B on the glass formation of Cu 60Pr 30Ni 10Al 10–2xTi xB x( x = 0, 0.05%(atom fraction) amorphous alloys was investigated using differential scanning calorimetry (DSC) and X-ray diffraction (XRD). XRD analysis showed that microalloying with 0.05% Ti and 0.05% B improved the glass forming ability (GFA). The smaller difference in the Gibbs free energy between the liquid and crystalline states at the glass transition temperature (Δ G 1-x( T g) and the smaller thermodynamic fragility index (Δ S f/ T m, where Δ S f is the entropy of fusion, and T m is the melting temperature) after microalloying correlated with the higher GFA.
