Abstract

A series of Ti44Cu44−xCo4Zr6Sn2Bex bulk metallic glasses with x=0–5.1 has been systematically investigated in terms of glass-forming ability and mechanical properties at room temperature. With the small amount of Be addition, the glass forming ability as well as ductility can be significantly increased leading to the fully amorphous rod having the diameter larger than 4 mm and ductility larger than 10%. Upon compressing the bulk metallic glass Ti44Cu38.9Co4Zr6Sn2Be5.1, a work hardening-like behavior that may be attributed to structural heteorgeniety was observed.
