Abstract

A method of consolidating particulate materials into articles having combinations ofproperties not available by conventional processes by liquid phase sintering. Theseparticulate materials are comprised of core particles individually coated withlayers of a metal compound having a relatively higher fracture toughness thanthe core, such as WC or TaC. These coated particles include an outer layer compriseda metal, such as Co or Ni. The particles with these coatings are pressed to forman article and the article densified at pressures and temperatures where fulldensity is achieved without the degradation of the material forming the coreparticle.
