The hardened phase is a transition metal carbide in the periodic table, such as tungsten carbide, titanium carbide, and tantalum carbide. Their hardness is high, the melting point is above 2000 \u00b0C, and some even exceed 4000 \u00b0C. In addition, nitrides, borides, and silicides of transition metals have similar properties and can also act as hardened phases in cemented carbides. The presence of the hardened phase determines the alloy’s extremely high hardness and wear resistance. The binder metal is generally an iron group metal, and cobalt and nickel are commonly used.<\/div>\n
