Dynamic Tensile Strength Limit of BL-Group Ceramic Matrix Composites Synthesized in the cBN–Carbide–Al System

The dynamic tensile strength limit \(R_{m}^{d}\) of superhard BL-group ceramic materials synthesized by HPHT sintering in the cBN–TiC–Al, cBN–TiCN–Al, cBN–TiC–WC–Al, cBN–Ti₄WC₅–Al, and cBN–NbC–Al systems has been investigated. It has been shown that \(R_{m}^{d}\) of these composites is ranged within 271–378 MPa, being quite sufficient for their use in cutting tools for metalworking.

期刊介绍： Journal of Superhard Materials presents up-to-date results of basic and applied research on production, properties, and applications of superhard materials and related tools. It publishes the results of fundamental research on physicochemical processes of forming and growth of single-crystal, polycrystalline, and dispersed materials, diamond and diamond-like films; developments of methods for spontaneous and controlled synthesis of superhard materials and methods for static, explosive and epitaxial synthesis. The focus of the journal is large single crystals of synthetic diamonds; elite grinding powders and micron powders of synthetic diamonds and cubic boron nitride; polycrystalline and composite superhard materials based on diamond and cubic boron nitride; diamond and carbide tools for highly efficient metal-working, boring, stone-working, coal mining and geological exploration; articles of ceramic; polishing pastes for high-precision optics; precision lathes for diamond turning; technologies of precise machining of metals, glass, and ceramics. The journal covers all fundamental and technological aspects of synthesis, characterization, properties, devices and applications of these materials. The journal welcomes manuscripts from all countries in the English language.
