Abstract
The disclosure provides Pt—P metallic glass-forming alloys and metallic glasses comprising at least two of Ni, Pd, Ag, and Au and optionally Si as well as potentially other elements, where the weight fraction of Pt is between 74 and 91 percent, and where the at least two of Ni, Pd, Ag, and Au contribute to increase the critical rod diameter of the alloy in relation to a Pt—P alloy free of Ni, Pd, Ag, and Au or a Pt—P alloy comprising only one of these elements. In embodiments where the PT850 hallmark is satisfied, alloys according to the disclosure are capable of forming metallic glass rods with diameters in excess of 3 mm, and in some embodiments 30 mm or larger.
