FIELD: powder metallurgy, namely production of powder molybdenum-copper pseudo alloys.
SUBSTANCE: method comprises steps of preparing charge in high-power ball type planetary grinder with centripetal acceleration of grinding bodies no less than 40g at least for 10 min; pressing prepared charge by effort no more than 150MPa; sintering it stage by stage in hydrogen atmosphere; initially heating till temperature of reduction soaking at least up to 800°C; soaking for time period no less than 1 h; going on heating till final sintering temperature at rate no more than 10°C/min and soaking at least for 0.5 h.
EFFECT: possibility for producing material having percentage density no less than 98% and low difference degree of density.
