Formation of Ti–Zr–Cu–Ni–Sn–Si bulk metallic glasses with good plasticity

Formation and mechanical properties of Ti–Zr–Cu–Ni–Sn–Si glassy alloys consisting of dissimilar and similar elements are studied. Ti45.8Zr6.2Cu39.9Ni5.1Sn2Si1 glassy alloy can be prepared in a bulk glassy rod form of 4 mm in diameter and exhibits strength of 2100 MPa and a plastic strain of ∼5% prior to failure in compression. The plasticity of the Ti45.8Zr6.2Cu39.9Ni5.1Sn2Si1 bulk metallic glass is attributed to the deformation-induced nanocrystallization in the glassy matrix during compression.
