PRODUCTION OF SHEETS AND PLATES FROM ALUMINIUM ALLOYS Russian patent published in 2014 - IPC C22F1/47 C22C21/06 

FIELD: metallurgy.

SUBSTANCE: proposed method comprises production of ingot from aluminium alloy containing magnesium and rhenium by semicontinuous casting. Homogenising annealing is performed at 300-360°C for up to 8 hours and ingot is machined. Cast ingots are heated to 340-380°C for up to 8 hours for rolling. Hot rolling to sheet or strip is performed as well as subsequent annealing at 380-440°C for up to 4 hours.

EFFECT: high mechanical properties at the room and lower temperatures.
