Структура порошков WC, обработанных ударными волнами

Abstract

In the cylindrical tree-contour of saving dusts WC are treated by shock waves. Shock waves were generated at explosion of an explosive charge of makeup TG50, which speed of a knocking of 7.3 km/s, pression in a detonation wave 20 GPa. After handling the substructure, parameters of a lattice a method of radiography studied fractional makeup of dusts a method of scanning electron microscopy. It is fixed, that shock-wave handling of dust WC results in change of fractional makeup at the expense of crushing out of particles. Features of x-ray diffraction curved lines allow counting, that in particles there is nano dispersible a component with the size of grains about 4 nm in an amount up to 60 %. Varies, the periods of a lattice and volume of a low level cell.
