  • Multi carbide alloy for bimetallic cylinders
    Patent number: 5246056
    Abstract: The present invention relates to alloys having substantially uniform aggregate distribution, a method of making such alloys, and centrifugally cast members made from such alloys. The alloys of the present invention utilize aggregates of tungsten carbide, vanadium carbide and titanium carbide so formulated to allow them to be uniformly distributed throughout the alloy matrix.
    Type: Grant
    Filed: June 10, 1991
    Date of Patent: September 21, 1993
    Assignee: Bimex Corporation
    Inventors: Donald P. Lomax, Gregory N. Patzer, Giri Rajendran

  • Heat treated high strength bimetallic cylinder
    Patent number: 4596282
    Abstract: A high strength bimetallic cylinder having a wear-resistant ferrous liner or inlay and capable of withstanding high stresses is provided by a heat treatment process wherein the cylinder steel is transformed into the austenitic phase, followed by rapidly cooling the cylinder to an intermediate temperature so that the ferrous outer housing is transformed to a bainitic structure, and then slowly cooling the cylinder to transform the ferrous liner into a martensitic structure.
