FIELD: powder metallurgy. SUBSTANCE: method to produce sintered pieces from diffusion alloyed iron powder provides for preparation of charge, pressing and sintering. Charge is prepared in two stages: first they produce nickel and molybdenum diffusion alloyed iron powder, exercise reducing annealing of mixture under temperature of 720 C within 3 hours, Then copper powder is added to produced reducing mixture. Pieces sintering is exercised under temperature of 1160 C. Nickel oxide is used as nickel-having addition. EFFECT: improved quality of pieces. 2 cl, 1 tbl
