Abstract
The effect of Cu content on glass transition behavior of (La0.5Ce0.5)65Al10Co25-xCux (xâ¯=â¯0, 5, 10, 15, 20, 25) metallic glasses was measured by high-rate and high-precision differential scanning calorimetry. It is observed that the glass transition temperature (Tg) decreases with the increase of the Cu content. The fragility (m) increases first and then decreases with the increasing of Cu content, with a maximum mâ¯=â¯63.6 for xâ¯=â¯10. A correlation is confirmed between the enthalpy of mixing fragility. These results suggest that metallic glasses with desirable supercooled liquids characters can be designed by alloying elements with suitable mixing enthalpy.
