Abstract

The peculiarities of structural-phase and physical-chemical transformations, which are initiated by high voltage electric discharge in composite Fe-Ti-C powders suspension in hydrocarbon fluid, are researched. Laws of communication between the treatment parameters and the dispersion and phase composition of obtained powders are found. It is shown that electric discharge treatment of initial powders leads to the increase of consolidated material hardness. Full text download
