Room-temperature mechanical properties and glass formation of Zr_(50)Cu_(20)Ni_(15)Al_(15-x)Ti_x (x=3, 5, 7) bulk metallic glass alloys

摘要

In the present study, the Zr-Cu-Ni-Al based bulk metallic glasses with different Ti addition was successfully prepared by suction casting. It was found that the glass forming ability was improved with increasing of Ti content from 3 at.% to 7 at.%. However, with increasing of Ti content, the room-temperature plasticity decreased from 4.33% to 0.66%.
