Patents by Inventor Sherman M. Snyder

Sherman M. Snyder 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).

  • High strength cast+HIP nickel base superalloy
    Patent number: 4888253
    Abstract: A nickel base superalloy composition useful in the cast+HIP+heat treated condition is described. Articles having the invention composition have properties which are significantly better than similarly processed IN718 articles. This is achieved by modifying the chromium, columbium, and titanium contents in the alloy composition, relative to the IN718 composition.
    Type: Grant
    Filed: December 30, 1985
    Date of Patent: December 19, 1989
    Assignee: United Technologies Corporation
    Inventors: Sherman M. Snyder, Edgar E. Brown
  • Laves free cast+hip nickel base superalloy
    Patent number: 4750944
    Abstract: A nickel base superalloy composition useful in the cast+HIP+heat treated condition is described. Articles having the invention composition have properties which are comparable to similarly processed IN718 articles. The invention alloys have an as-cast microstructure which is substantially free from Laves phase, even at slow solidification rates. As a result, the alloys are significantly more weldable than IN718. This desirable microstructure is achieved by modifications of the chromium, molybdenum, iron, and nickel contents compared to the typical IN718 composition.
