The phase structure of surfaces of steel samples, modified by pulseplasma processing, was analyzedusingXRD and metallographic methods. It has been shown, that after pulse plasma processing under different conditions a modified structure consisting of three new phases, including austenite, ironnitride and carbide, is formed. The dependence of phase transition and micro hardness on plasma flow parameters has been studied. A sharp decrease in the dimensions of ferrite crystallites aftertheimpact of plasma flow is observed. The main purpose of hardening of carbon steel samples is formation of nano-dimension ferrite with oriented iron carbide on grains.Pulse plasma accelerators are effective sources of plasma streams. To take such plasma streams it is used in researches in thermonuclear power and in processing of materials with the purpose to improve properties of materials. PPA appeared earlier than other accelerators and made a contribution to development and use of plasma accelerators in different spheres of science and equipment. Sense of technical use of plasma accelerators that with their help it is possible to take a stream of particles the having wide range of speed and energy.
