  • Class of ductile iron, and process of forming same
    Patent number: 5522949
    Abstract: A new class of ductile iron is formed by the hot isostatic pressing of a ductile iron casting, followed by austempering of the ductile iron casting. Hot isostatic pressing can be carried out at a pressure in the range of 10,000 to 17,000 psi at a temperature above 1600.degree. F., and usually in the range of 1850.degree. F. to 2050.degree. F. Austempering of the material is carried out by heating to the austenitizing temperature (about 1500.degree. F. to 1800.degree. F.), maintaining the austenitizing temperature for a suitable time period, and rapidly cooling to an austempering temperature (about 400.degree. F. to 750.degree. F.) to form ausferrite within the sample.
