Popis: All industrial alloys of the Al−Mg system correspond to the region of the α-solid solution of the phase diagram. Domestic alloys AL8 and AL27-1 and foreign alloys 520 (USA) and LM-10 (Great Britain) with a high magnesium content (9–11%) have high mechanical properties after quenching. However, they possess a high sensitivity to natural aging under conditions of long-term operation or storing, which causes their embrittlement. The aim of the present work consists in developing an Al−Mg-base composition quenched and aged artificially that will possesses a high strength (σ t =380-400 N/mm2) and will not change in operation at a temperature of at most 100°C.
