METHOD FOR INCREASING MECHANICAL STABILITY AND STRENGTH OF SHEET Billets FROM ALUMINUM-MAGNESIUM ALLOYS USING THE ELECTROPLASTIC DEFORMATION EFFECT

摘要

FIELD: metallurgy.SUBSTANCE: method of processing sheet blanks from industrial aluminium alloys of the Al-Mg system involves machining the workpiece while simultaneously passing a constant electric current of density greater than 30 A/mmup to 50 A/mmfor suppressing the formation of a strip and intermittent deformation with a simultaneous increase in the strength of the alloy.EFFECT: invention makes it possible to reduce energy costs for metalworking, improve the quality of the surface to be treated, increase the service life and improve the fuel efficiency of aluminium-magnesium alloys used in the manufacture of aerospace machinery and cars.6 dwg
