Влияние условий предварительного деформирования порошков BNв перед спеканием на формирование структуры и свойства ПСТМ

Abstract

Influence of deformation conditions of wBN powders by rolling before sintering on structurization and properties formation of PSHM is investigated. Application of the directed powder rolling promoting oriented stacking of particles by basic surfaces is shown, that, provides to a material sintered in same conditions, increase of durability shock loads at turning hardened steels in comparison with PSHM from wBN rolled with an intermediate graining.
