Влияние свойств микропорошков кубического нитрида бора на характеристики спеченных на их основе композитов и поликристаллов

Abstract

Properties of cBN micron powders prepared in various growth systems have been studied as loose powders and in composites and polycrystals sintered of them at high pressure and temperature. It has been found that mechanical properties of the composites and polycrystals, including their cutting characteristics, depend not only on the initial powders properties, but also on the method of producing the composites and polycrystals and conditions of testing them.
