FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy field. Particularly it relates to thermomechanical treatment of magnesium alloys and can be used while manufacturing of details in aircraft building, rocket technology, motor car structure, in nuclear reactors. Method includes alloy homogenising annealing at the temperature 415-520°C during 4-24 hours, extrusion at the temperature 300-450°C with drafting ratio 7-18 and equal channel angular extrusion at the temperature 250-320°C with true deformation ratio 6-8.
EFFECT: increasing of solidity and plasticity of magnesium alloys.
