METHOD FOR TREATING MG-AL-ZN MAGNESIUM ALLOY USING ROTATIONAL FORGING METHOD Russian patent published in 2018 - IPC C22F1/06 

FIELD: metallurgy.

SUBSTANCE: invention relates to magnesium based alloys, in particular to methods for deformation treatment of magnesium alloys, and can be used to produce products used as structural materials in aviation, rocketry, transport, etc. This method for processing magnesium alloys of the Mg-Al-Zn system comprises a preliminary heat treatment by homogenizing annealing at a temperature of 450–500 °C and rotary forging, wherein the rotary forging is performed stepwise in the temperature range of 400–350 °C with a total true degree of deformation of 2.5–3, wherein the forging at each stage is carried out at a temperature that is 25 °C below the temperature of the previous stage until the required structure is obtained, consisting of grains with an average size of less than 5 microns, full of deformation twins.

EFFECT: technical result of the invention is to increase the strength of magnesium-based alloys of the Mg-Al-Zn system while simultaneously increasing their plasticity.
