Abstract: A liquid phase sintered dense composite body comprising a hard refractory metal carbide which is densely cemented by sintering with a metal or alloy components. The sintered composite body incorporates at a surface or in the interior a multiplicity of metallic elements consisting of coarse grains, strands and/or plates of either the same metal or alloy as the cementing component or metallic elements having a melting point at least 120.degree. C. higher than the temperature at which the liquid phase takes place on sintering. This liquid phase sintered dense composite body is manufactured by placing the coarse grains, strands and/or plates on the surface or within the compacted powder mixture prior to the liquid phase sintering operation.

Abstract: A liquid phase sintered body for brazed joints having a multiplicity of pores, grooves and/or indented patterns formed on a desired surface. The liquid phase sintered body is produced by a method comprising the steps of forming a compact body of a mixture of a hard refractory material, such as carbides, nitrides, oxides, borides and silicides mixed with cementing metal in powder form, placing on the desired surface any one of coarse grains, strands or plates of a metal having a diameter or a thickness over ten times as great as the grain size of the cementing metal, and sintering the compact body under conditions suitable for melting the coarse grains, strands and/or mesh of strands or plates after densification of the compact body has been completed or substantially completed. The metal forming the coarse grains, strands or plates must have a melting point which is more than 50.degree. C.
