US Patent 7122069 Mo-Cu composite powder

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.
