Sintered body for use in a cutting tool and the method for producing the same

摘要: The invention relates to a sintered body for use in cutting tool comprising edge forming part having particularly high hardness and wear resistance bonded supporting member plastic deformability, stiffness, transverse rupture strength, thermal conductivity, expansion coefficient, corrosion, oxidization the like, method producing same. A diamond powder or pressure form boron nitride is placed contact with preliminarily cermet constituted by carbide crystals chiefly molibdenum of (Mo, W)C iron group metals, combined being at temperature under which thermodynamically stable so that thereby enabling obtain said properties tool.
