The disclosure provides Zr&#x2014;Ti&#x2014;Cu&#x2014;Ni&#x2014;Al metallic glass-forming alloys and metallic glasses that have a high glass forming ability along with a high thermal stability of the supercooled liquid against crystallization.

Zirconium-titanium-copper-nickel-aluminum glasses with high glass forming ability and high thermal stability

A rapid discharge heating and forming apparatus is provided. The apparatus includes a source of electrical energy and at least two electrodes configured to interconnect the source of electrical energy to a metallic glass sample. The apparatus also includes a shaping tool disposed in forming relation to the metallic glass sample. The source of electrical energy and the at least two electrodes are configured to deliver a quantum of electrical energy to the metallic glass sample to heat the metallic glass sample. The shaping tool is configured to apply a deformational force to shape the heated sample to an article. The at least two electrodes have a yield strength of at least 200 MPa, a Young's modulus that is at least 25% higher than the metallic glass sample, and an electrical resistivity that is lower than the metallic glass sample by a factor of at least 3.

Durable electrodes for rapid discharge heating and forming of metallic glasses

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;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.
