METHOD OF THE THERMAL TREATMENT OF THE SHEETS AND WELDED JOINTS OF THE ALUMINUM-MAGNESIUM-SILICON ALLOYS SYSTEM Russian patent published in 2006 - IPC C22F1/47 

FIELD: metallurgy; methods of the thermal treatment of sheets and welded joints of the aluminum-magnesium-silicon alloys system.

SUBSTANCE: the invention is pertaining to metallurgy, in particular, to the methods of the thermal treatment of sheets and welded joints of the aluminum-magnesium-silicon alloys system. The method provides for heat hardening at the temperatures from 525-530°C with refrigeration in water and tempering. The tempering is conducted at the temperatures of 180-200°C with the time of aging for 1.0-3.5 hour. The technical result of the invention is reduction of duration of the heat treatment of the sheets and the details produced out of them by the cold stamping and also their welded joints.

EFFECT: the invention ensures reduction of duration of the heat treatment of the sheets and the details produced out of them by the cold stamping and also their welded joints.
