New Au-based bulk glassy alloys with ultralow glass transition temperature

Abstract

New Au-based glassy alloys with high Au contents of ∼60–70 at.% have been found to exhibit an ultralow glass transition temperature (∼66–86 °C), a high glass-forming ability and a wide supercooled liquid region. They also have high thermodynamic and kinetic stability in the supercooled liquid state, strong oxidation resistance , good mechanical properties , very high corrosion resistance and excellent thermoplastic formability.
