  • Method for producing an at least partly amorphous alloy piece
    Patent number: 4797166
    Abstract: An alloy, e.g. a Cr-Ti alloy, is transformed to a metastable crystal modification, e.g., by heating in an electric arc and quenching in water. The metastable crystal modification is annealed at a temperature which is below the glass temperature, e.g. at 600.degree. C. during 48 hours, causing it to vitrify completely.The inventive method provided the production of large pieces of hard and non-porous amorphous alloy with thicknesses in the centimeter range.
