Abstract
The thermal stability, melting behavior, and glass-forming ability of Zr 70Al 8Cu 22− x Ni x ( x = 3–19 at.%) metallic glasses were investigated. Fully glassy sample with largest critical diameter of 10 mm was obtained for alloy with x = 8.5 in the alloy series, which corresponds to a deep eutectic, largest supercooled liquid region, and largest γ value. Room temperature compression test revealed that the monolithic Zr 70Al 8Cu 13.5Ni 8.5 bulk metallic glass exhibits a high yield strength of 1570 MPa, a Young's modulus of 80 GPa, and a super large plastic strain more than 70%.
