Abstract:The thermal stability, melting behavior, and glass-forming ability of Zr(70)Al(8)Cu(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 gamma value. Room temperature compression test revealed that the monolithic Zr(70)Al(8)Cu(13.5)Ni(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%.
