COMPOSITE MATERIALS - CEMENTED CARBIDE-METAL ALLOY Russian patent published in 2013 - IPC C22C29/00 B22F7/02 

FIELD: metallurgy.

SUBSTANCE: composite product includes the first area metallurgically related to the second area having the thickness of more than 100 mcm. The first area includes the material from cemented solid particles, in which there is at least 60 vol. % of solid particles. The second area includes metal or metal alloy chosen from the group containing steel, nickel, nickel alloy, titanium, titanium alloy, molybdenum, molybdenum alloy, cobalt, cobalt alloy, tungsten and tungsten alloy, and solid particles of 0 to 50 vol. %. The product is produced by pressing and sintering of the first metal powder containing solid particles and powder-like binding agent, and the second metal powder containing metal or metal alloy, and solid particles of 0 to 50 vol. %.

EFFECT: high strength of connection between composite areas owing to eliminating defects at the boundary line, and high tensile strength.
