The technological methods of obtaining the mix of the 75 % Fe + 20 % Tі + 5 % B4C (wt%), 80 % Fe+20 % Ti (wt%) initial elementary powders by the high-voltage electrodischarge dispersion (HED) in the clarified kerosene accompanied by the synthesis of polydisperse micro- and nano-size powder compositions of the iron-carbon alloy - titan carbide (diboride) system. The theoretically justified mode of electrodischarge sintering (EDS) of the iron-carbon alloy - titan carbide (diboride) system was reproduced. It is shown by experiments that at the same pressure of 50 MPa, the temperature rise rate of 1,65 K/s and holding time from 800 to 820 С the products of various structures and properties can be obtained by changing the harmonious current composition. The technology of obtaining the high-abration-resistant composites like carbide steels is developed with use of the technological scheme of hot forming of porous blanks of micro- and nanosize composite powders after the electrodischarge treatment of the mix of Fe-Tі-B4C micropowders in kerosene. Physicomechanical tests of hot-formed products revealed the level of high bend strength ~ 1,960 MPa, the post-quenching hardness from 68 to 71 HRC and impact strength ~ 52 kJ/m2.
