FIELD: powder metallurgy, namely production of hard alloys, possibly manufacture of cutters and abrasive tools. SUBSTANCE: method for making composite materials on base of borides and carbides of metals of IV-VI, VIII groups comprises steps of using CBC - composition powder as initial powder; subjecting such powder to mechanical activation in gasoline at relation of mass of balls to powder mass equal to 20 : 1; carrying out pressing and further agglomeration in vacuum at initial porosity of pressed blank 25 - 30% and temperature 1270 -1300C during 30 - 40 min. EFFECT: enhanced strength and abrasive capability of products. 1 tbl, 1 ex
