FIELD: manufacture of hard alloy cermet articles and tools for different designations. SUBSTANCE: method comprises steps for preparing components of charge; disintegrating, mixing and loading charge into form, molding and sintering it at heating, soaking at predetermined sintering temperature. According to one variant of invention sintered article is subjected to cooling until temperature (1250-900) C at cooling rate no more than 3 C/s. Further cooling is carried out in quenching mode at cooling rate no less than 3 C/s until temperature +300 C - (-196) C. Then product is subjected to stabilization annealing by heating it up to maximum temperature consisting 0.35-0.5 of maximum temperature value of quenching mode. And then article is cooled. Two more variants of invention are offered. EFFECT: possibility of making products with increased hardness, high wear resistance and long service life. 26 cl, 2 tbl, 3 ex
