摘要：
A Ti43Zr7Cu43Ni7 bulk metallic glass (BMG) exhibits a plastic strain of less than 0.2% under room-temperature compression. However, a Ti45Zr5Cu40Ni7.5Sn2.5 BMG developed by addition of Sn to Ti43Zr7Cu43Ni7 shows a significant improvement of similar to 14.8% to the plastic strain with work hardening. Microstructural comparison of these BMGs reveals that the addition of Sn leads to formation of nano-scale chemical heterogeneities throughout the material. These nano-scale chemical fluctuations play an important role in enhancing the plastic strain of (Ti-Cu)-based BMGs.
