Zusammenfassung:	FIELD: manufacture of hollow articles from aluminum alloys which are hardened by heat treatment. ^ SUBSTANCE: proposed method consists in manufacture of hollow semi-finished product which is subjected to pressure shaping at change of perimeter of cross section of freshly hardened hollow semi-finished product at permissible degree of deformation. ^ EFFECT: enhanced accuracy of articles at lesser roughness of surface. ^ 2 ex
