METHOD OF PRODUCING DOPPED IRON ALLOY FROM PRODUCTION WASTES Russian patent published in 2011 - IPC C21B15/02 B22F3/23 C22C38/00 

FIELD: technological processes.

SUBSTANCE: invention relates to powder metallurgy, particularly to methods of producing doped iron alloys from iron-containing production wastes. The method of producing a doped iron alloy involves mixing iron dross in amount of 70-80 wt % and aluminium powder in amount of 15-20 wt % to obtain a thermite mixture, and melting the thermite mixture via self-propagating high-temperature synthesis. While stirring, the following is added to the obtained thermite mixture: titanium carbide in amount of 10-15% of the weight of the thermite mixture, chromium in amount of 10-15% of the weight of the thermite mixture and silicobarium foundry alloy FS65Ba₄ in amount of 2-3% of the weight of the thermite mixture.

EFFECT: invention enables to obtain doped alloys with predetermined compositions and required properties, used to increase resistance of an impact tool, as material for cold deforming dies, and low costs on producing said alloys.
