Non-isothermal crystallization kinetics and glass-forming ability of Cu-Zr-Ti-In bulk metallic glasses

► The as-cast alloys have a good stability in thermodynamics depending on activation energies. ► Activation energies corresponding to own exothermic peaks for both z = 1 and z = 5 are similar. ► Cu54Zr37Ti8In1 is “strong glasses” and others are “intermediate glasses”. ► Glass-forming ability of the as-cast alloys increase with the content of In element.
