Abstract

There are no reported gold-rich alloys that are both readily glass forming(RGF) upon rapid solidification processing (RSP) and, in the glassy state,have crystallization temperatures Tc sufficiently high to insurelong metastable life times at room temperature. A representative of a newfamily of ternary gold-based glasses is described that contain Cu and a rareearth (RE) Metal (or Y), with total addition element concentrations as lowas 15 at. pet., and its crystallization characteristics are reported. UnderRSP processing by arc furnace hammer-and-anvil quenching, the alloy Au0.80Cu0.10Y0.10 readily forms aductile glass, with Tc = 685 K, ΔHc = 1.25 kJ/g-Moleand an activation energy of crystallization ΔE3 (cryst.) = 190kJ/g-Mole.
