METHOD OF PRODUCING BAR IRON OF MAGNESIUM ALLOYS OF MG-AL SYSTEM Russian patent published in 2017 - IPC C22F1/06 C22C23/02 B21C23/04

Abstract RU 2631574 C1

FIELD: metallurgy.

SUBSTANCE: method for producing bar iron from magnesium-based alloy of Mg-Al system includes hot deformation by longitudinally rolling round bars in 6 passes with a total value of logarithmic deformation e=1.6, wherein rolling is carried out at a constant speed in calibers "circle-oval-circle" in the area of recrystallization temperatures with quenching of billet into water during the transition from one caliber to the next and subsequent heating to the rolling temperature, with workpiece rotation around the rolling axis on 90° after each pass.

EFFECT: increase in strength properties for the yield point, while decreasing the anisotropy coefficient of strength properties relative to the initial state.
