Температурная зависимость микротвердости композитов на основе алмазного нанопорошка детонационного синтеза

Abstract

Results of studying of hardness, fracture toughness and temperature dependence of microhardness of composites based on diamond nanopowder of detonation synthesis UDD and carbides of transitive metals, and also, polycrystals sintered from diamond nanopowder of static synthesis are considered. It is shown, that composite UDD–WC has the highest level of physicomechanical properties.
