The disclosure is directed to Ni&#x2014;P&#x2014;Si alloys bearing Mn and optionally Cr, Mo, Nb, and Ta that are capable of forming a metallic glass, and more particularly demonstrate critical rod diameters for glass formation greater than 1 mm and as large as 5 mm or larger.

Bulk nickel-phosphorus-silicon glasses bearing manganese

The disclosure provides Pt&#x2014;Cu&#x2014;P glass-forming alloys bearing at least one of B, Ag, and Au, where each of B, Ag, and Au can contribute to improve the glass forming ability of the alloy in relation to the alloy that is free of these elements. The alloys are capable of forming metallic glass rods with diameters in excess of 3 mm, and in some embodiments 50 mm or larger. The alloys and metallic glasses can satisfy platinum jewelry hallmarks PT750, PT800, PT850, and PT900.

Bulk platinum-copper-phosphorus glasses bearing boron, silver, and gold

Ni&#x2014;Cr&#x2014;Nb&#x2014;P&#x2014;B alloys and metallic glasses are provided, where Nb and B are varied such as to achieve alloys with good glass forming ability that form metallic glasses which may exhibit unexpectedly high strength and/or high thermal stability of the supercooled liquid. Specifically, the alloys of the current disclosure are capable of forming metallic glasses and have critical rod diameters of at least 3 mm, while the metallic glasses exhibit yield strength greater than 2550 MPa and stability of the supercooled liquid of at least 45&#xb0; C.

Bulk nickel-chromium-phosphorus glasses bearing niobium and boron exhibiting high strength and/or high thermal stability of the supercooled liquid

Ni&#x2014;Fe, Ni&#x2014;Co, and Ni&#x2014;Cu-based bulk metallic glass forming alloys are provided. The alloys have critical rod diameters of at least 1 mm and in some instances at least 11 mm. The alloys have composition according to NiXCrNbPB, wherein X is at least one of Fe, Co, and Cu, the atomic percent X (Fe and/or Co and/or Cu) ranges from 0.5 to 30, the atomic percent of Cr ranges from 2 to 15, the atomic percent of Nb ranges from 1 to 5, the atomic percent of P ranges from 14 to 19, the atomic percent of B ranges from 1 to 5, and the balance is Ni.
