▎ 摘　　要

NOVELTY - A cemented carbide alloy consists of a sintered compact obtained by sintering a raw material powder obtained by adding a transition metal powder to tungsten carbide powder. The sintered compact comprises carbon nanotubes and graphene. USE - Cemented carbide alloy. ADVANTAGE - The cemented carbide alloy has excellent fracture toughness, durability, strength, and hardness. Changing of all added carbon nanotubes to graphene is suppressed. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of cemented carbide alloy. DESCRIPTION OF DRAWING(S) - The drawing shows an enlarged view of the structure of cemented carbide alloy. (Drawing includes non-English language text)
