Web1 de jan. de 2024 · The highest hardness is exhibited by the sample exposed to 650 °C (455 HV10) and it exceeds the hardness in hot-rolled state by 130 HV. Moreover, CP of γ’ observed after exposure to 700 °C did not cause an increase in hardness (430 HV10). WebMetal carbides have high hardness and high hot hardness, which makes them useful for cutting tools, forming dies, and other wear applications. Metal carbides often use cobalt, nickel, or intermetallic metal bonds between grains (cemented carbides), which results in increased toughness compared a pure carbide or ceramic.
