The goal of modern scientific research is focused on the elaboration of energy and resource saving, ecologically safe technologies for production new materials,. In this point one of the prospective direction for reduction of electrical energy and the duration of technological cycle is the Self-propagating High-temperature Synthesis (SHS). The work describes some characteristics of phase formation in Ti-Cr-C-Me and Ti-Cr-C-Mo-Me systems by SHS technology. It is shown that physical and mechanical properties of hard alloys, in particular exploitation strength. In the presented work the possibility of increasing adhesive strength among I, II and III phases in Ti-Cr-C-X18H15 system is studied.The other typical property of hard alloys is their resistance in different media, especially resistance against oxidation on air at high temperatures. Such materials can be used for preparation of stamps, high-temperature isostatic stamping, rolls, cutting tools, peep-holes and etc.

Increasing interest of science is the study of possibility to obtain composites that can be used in chemical, radio electronics, machine-building and aviation industries. The specific attention is towards the materials which contain hard melting compounds of borides, carbides, nitrides, silicides, also their combination and their compounds with oxygen. The main goal of the work was obtaining ultra dispersed powders at recovery stage from the following composites: BN, B4C, BxNyCz, SiC, TiB2, SiC-Al2O3 by Self-propagating High-temperature Synthesis (SHS). The efficiency and competitiveness of materials obtained by energy saving SHS technology is provoked by the use of cheap raw materials and simple equipment, compared to traditional methods for obtaining analogue materials. The technological bases for production ultra dispersed powder compounds has been elaborated, which have particular role and find wide application in industry because of the unique complex of properties, such as hardness, thermal stability, abrasive wear resistance and corrosion resistance.
