Patents by Inventor Morris E. Fine

Morris E. Fine 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).

  • Alloys and methods of forming same
    Patent number: 11198926
    Abstract: In one aspect of the invention, an alloy includes a first element comprising magnesium (Mg), titanium (Ti), zirconium (Zr), chromium (Cr), or nickelaluminum (NiAl), a second element comprising lithium (Li), calcium (Ca), manganese (Mn), aluminum (Al), or a combination thereof, and a third element comprising zinc (Zn). According to the invention, nanoscale precipitates is produced in the magnesium alloy by additions of zinc and specific heat-treatment. These precipitates lower the energy for dislocation movements and increase the number of available slip systems in the magnesium alloy at room temperature and hence improve ductility and formability of the magnesium alloy.
    Type: Grant

    Date of Patent: December 14, 2021
    Assignee: NORTHWESTERN UNIVERSITY
    Inventors: Morris E. Fine, Semyon Vaynman, Evan T. Hunt, Akio Urakami, Yip-Wah Chung, Johannes Weertman

  • Method of making copper-titanium nitride alloy
    Patent number: 5338374
    Abstract: A process for forming a copper alloy which is strengthened while maintaining good electrical and thermal conductivity by the addition of TiN or ZrN consists of external nitridation of a mechanically alloyed powder mixture followed by further mechanical alloying to break down the surface coating which forms during nitridation.
