Beschreibung
Zusammenfassung:	FIELD: metallurgy. SUBSTANCE: method of production of sheets and bands from aluminium alloys containing copper and lithium includes hot rolling of ingot, stepped annealing with intermediate cooling under the following conditions: heating to temperature within region T2 (T2(Al6CuLi3)), holding for 0.1-2 h, heating to 230-420 C, holding for 1-5 h, cold rolling, hardening, straightening and ageing. EFFECT: higher reliability of operator of manufactured articles after operating and process heatings. 1 tbl
