Abstract

A dimensional region of the existence of WC nanoparticles and nanostructured WC-Co hard alloys has been substantiated. It has been shown that the existing technologies do not allow to obtain pore- free WC-Co hard alloys with carbide particles of size 5–40 nm to be produced. A method of the formation of nanostructured hard alloys has been proposed.
