Abstract
Au40Si17.20Cu28.30Ag5.7Pd 5 glassy alloys showed a wide supercooled liquid region of 42-53 K and a large reduced glass transition temperature of 0.568-0.605, indicating high stabilization of supercooled liquid and high glass-forming ability (GFA). The best GFA was obtained from Au40Si20Cu28Ag 7Pd5 alloy, and a fully glassy sample with a diameter of 6 mm could be fabricated by copper mold casting. The bulk glassy alloys exhibited very low Tg of 400-424 K, high fracture strength of over 1100 MPa, and corrosion resistance superior to SUS316L in 1NH2SO4 solution.
