Thomas R. Bieler 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).

  • Methods for producing lead-free in-situ composite solder alloys
    Patent number: 7771547
    Abstract: Methods are disclosed for producing in-situ composite solders having a particulate intermetallic phase homogeneously distributed throughout the solder matrix. An eutectic solder is mixed with the components of the intermetallic phase, melted and rapidly cooled to form the desired solder. In-situ composite solder alloys formed by the disclosed method provide greater solder joint strength and fatigue resistance.
    Type: Grant
    Filed: December 8, 2003
    Date of Patent: August 10, 2010
    Assignee: Board of Trustees Operating Michigan State University
    Inventors: Thomas R. Bieler, Karatholuvu N. Subramanian, Sunglak Choi

  • Apparatus for the preparation of metal matrix fiber composites
    Patent number: 5891249
    Abstract: A method for producing continuous and discontinuous fiber metal matrix composites (CFMMC). The method uses aerosolization of finely divided metal powders in a controlled atmosphere which prevents explosions to coat the fibers and then the metal coated fibers are consolidated to form the CFMMC. The composites are useful as heat sinks for electrical components and in applications where a structural reinforced metal matrix composite is needed.
