Formatted abstract The glassy rod with a maximum sample thickness of 11mm and larger supercooled liquid region of 108K was successfully fabricated when substituting Cu with minor amount of Ag in the Cu–Zr–Al–Gd alloy system. The value of γ reaches a maximum of 0.418 for the Cu45.5Zr45Al7Gd2Ag0.5 bulk metallic glass (BMG) alloy. The high glass- forming ability (GFA) and larger supercooled liquid region are discussed from atomic size, negative mixing heat among constituent elements and thermodynamics.
