摘要: Powder metallurgy (P/M) methods have expanded in recent years to include net-shape fabrication of W-Cu components. Sintering compacts made from previous powders has led low density and copper bleedout. This paper presents test results on the consolidation a new powder containing particles composed tungsten-coated core. effectively eliminates bleedout at sintering thereby making possible manufacturing parts. Sintered articles are characterized by microstructural homogeneity properties comparable those infiltrated composites.
