James O. Stiegler 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).

  • Ductile aluminide alloys for high temperature applications
    Patent number: 4612165
    Abstract: Improved Ni.sub.3 Al alloys are provided by inclusion of boron, hafnium or zirconium, and in some species, iron.
    Type: Grant
    Filed: December 21, 1983
    Date of Patent: September 16, 1986
    Assignee: The United States of America as represented by the United States Department of Energy
    Inventors: Chain T. Liu, James O. Stiegler
  • Austenitic stainless steel alloys having improved resistance to fast neutron-induced swelling
    Patent number: 4158606
    Abstract: The present invention is based on the discovery that radiation-induced voids which occur during fast neutron irradiation can be controlled by small but effective additions of titanium and silicon. The void-suppressing effect of these metals in combination is demonstrated and particularly apparent in austenitic stainless steels.
    Type: Grant
    Filed: March 15, 1978
    Date of Patent: June 19, 1979
    Assignee: The United States Department of Energy
    Inventors: Everett E. Bloom, James O. Stiegler, Arthur F. Rowcliffe, James M. Leitnaker
