The objective of investigation - structural steels Х70, КА25, wear resistant cast iron, hard alloys. Purpose - improving the quality of metal products by optimizing the composition, structure and parameters of heat treatment. Research methods - metallographic, X-ray phase analysis, electron microscopy, hardness measurements and standard tests of mechanical properties. The first chapter studied character pattern formation in X70 steel during hardening and subsequent tempering at different temperatures, and make recommendations concerning the processing mode. The second section presents the results of studies of the microstructure, phase composition, the carbide phase of the new wear-resistant cast iron with spherical vanadium carbide. The third section studied the effect of the parameters of high-speed heating on the structure and mechanical properties of rolled steel AK25. The fourth section is devoted to the analysis of structure and properties of steel sheet metal 09G2S for subsequent use in the manufacture of transport equipment parts. The fifth section describes the effect of hardening the plasma jet on the microstructure, hardness of the tool from the hard alloys.
