Balathandan S. Pillai has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Metal alloy product and method for producing same
    Patent number: 6846369
    Abstract: A method for producing a cast aluminum alloy article having high strength and/or toughness is provided. The method includes providing a molten aluminum alloy, centrifugally casting the molten aluminum alloy to form a cast body; and hot isostatically processing the cast body to form a hipped body. The hipped body may optionally be solution heat treated to form a heat treated body, which may subsequently be precipitation hardened to further enhance the properties of the cast product as desired. The method allows the production of cast aluminum alloy articles having physical and mechanical properties similar to those obtained for articles produced from corresponding aluminum alloy chemistries by wrought techniques.
    Type: Grant
    Filed: September 7, 2000
    Date of Patent: January 25, 2005
    Assignee: Johnson Brass & Machine Foundry, Inc.
    Inventors: Steven A. Clark, Balathandan S. Pillai
