Phase relations, microstructure and mechanical properties of VC substituted WC-10Co cemented carbide alloys

Thermodynamic assessment of the Co–V and Co–V–C system

“…Although the ternary carbide, M 6 C, has been reported in the Co-W-C and Me-Co-C (Me = Ti, Ta, or Nb) systems and was modeled with the four-sublattice model Co 2 Me 2 (Co, Me) 2 C, no vanadium containing M 6 C carbide has been detected in the Co-W-C-V system [1,3]. All the binary intermediate phases; Co 3 M, CoM 3 , sigma, V 3 C 2 , V 2 C, and VC are adopted in the Co-V-C system in the present evaluation.…”

“…Knowledge of the phase relations and thermodynamic properties of the Co-V-C system is crucial in the development of WC-Co cemented carbides with VC added as WC grain growth inhibitor [1][2][3]. The liquid phase sintering production of WC-VC-Co cemented carbides involves a very careful control of the carbon and grain growth inhibitor content.…”

Dry Reciprocating Sliding Friction and Wear Response of WC–Ni Cemented Carbides

“…Tungsten carbide based cemented carbides are used in a variety of industrial environments for their excellent mechanical properties and outstanding wear resistance in combination with high toughness and heat stability [1,2]. Despite competition from pure engineering ceramics, WC cemented carbides are widely employed in tribological applications such as cutting tools [3][4][5], metal forming [6], mining [7], drilling [8] and machining [9,10], and even in the domain of aerospace [11,12].…”

High Resolution Electron Microscopy Study in ZrC-Doped WC-12 mass%Co Alloys

“…1,2) To maintain the grain size to be suitable, other carbides are often doped as grain growth inhibitors in practical products. [3][4][5][6][7] So far, various carbides effective for the inhibition have been investigated. The effectiveness previously reported has been shown to be VC > Cr 3 C 2 > NbC > TaC > TiC > ZrC$HfC.…”
