FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy, particularly, to producing articles from aluminium or magnesium alloys with nano- and sub micro crystalline structure, and articles made thereof. Proposed method comprises preliminary equal-channel angular pressing and subsequent strain-forming of articles thereof. Said equal-channel angular pressing is performed at deformation temperature and rate selected subject to alloy composition by preset relation while strain-forming is carried out by extrusion at room temperature and deformation rate selected subject to alloy composition by preset relation.
EFFECT: better manufacturability, higher strength and ductility.
