  • Aluminum/alkaline earth metal composites and method for producing
    Patent number: 8647536
    Abstract: A composite is provided having an electrically conducting Al matrix and elongated filaments comprising Ca and/or Sr and/or Ba disposed in the matrix and extending along a longitudinal axis of the composite. The filaments initially comprise Ca and/or Sr and/or Ba metal or alloy and then may be reacted with the Al matrix to form a strengthening intermetallic compound comprising Al and Ca and/or Sr and/or Ba. The composite is useful as a long-distance, high voltage power transmission conductor.
    Type: Grant
    Filed: August 4, 2011
    Date of Patent: February 11, 2014
    Assignee: Iowa State University Research Foundation, Inc.
    Inventors: Alan M. Russell, Iver E. Anderson, Hyong J. Kim, Andrew E. Freichs

  • Superabrasive boride and a method of preparing the same by mechanical alloying and hot pressing
    Patent number: 6432855
    Abstract: A ceramic material which is an orthorhombic boride of the general formula: AlMgB14:X, with X being a doping agent. The ceramic is a superabrasive, and in most instances provides a hardness of 40 GPa or greater.
    Type: Grant
