The thermal stability, melting behavior, and glass-forming ability of Zr70Al8Cu22-xNix (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 Zr70Al8Cu13.5Ni8.5 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%.
