Abstract

This work represents the results of phase composition and the mechanical properties of tungsten and titanium after high-intensity pulsed ion beam (HPIB) treatment. It was shown that nanoscale carbide particles are formed under the HPIB influence in the surface layers of metals. Raising the pulse number results in increase of volume fraction of the carbide phases. The microhardness is 1.5-2 times more than the initial value and wear resistance of the metals improves in response to alloying of tungsten and titanium with carbon atoms accompanied by the formation of carbides.
