  • Mo-Cu composite powder
    Patent number: 7122069
    Abstract: A Mo—Cu composite powder is provided which is comprised of individual finite particles each having a copper phase and a molybdenum phase wherein the molybdenum phase substantially encapsulates the copper phase. The composite powder may be consolidated by conventional P/M techniques and sintered without copper bleedout according to the method described herein to produce Mo—Cu pseudoalloy articles having very good shape retention, a high sintered density, and a fine microstructure.
    Type: Grant
    Filed: March 13, 2001
    Date of Patent: October 17, 2006
    Assignee: Osram Sylvania Inc.
    Inventors: Leonid P Dorfman, Michael J. Scheithauer, David L. Houck, Anna T. Spitsberg, Jeffrey N. Dann
