glasses (BMGs) are considered new structural materials due to their unique mechanical, physical and chemical properties [1-5]. It is reported that the glass forming ability (GFA), physical, chemical... forming ability of CuZrAl bulk metallic glass. As shown in Fig. 2, the exothermic peaks tend to be broadened with Y addition, indicating a possible slow-down in the kinetics of crystal nucleation......
