PROCEDURE FOR THERMAL TREATMENT OF ITEM OUT OF ALUMINIUM ALLOY AND FACILITY FOR IMPLEMENTATION OF THIS PROCEDURE Russian patent published in 2010 - IPC C22F1/04 C21D1/00 

FIELD: metallurgy.

SUBSTANCE: procedure for thermal treatment of item out of aluminium alloy consists in stages whereat item is subject to heat treatment for solid solution, to tempering, and to heating tempered item by preliminary ageing at stage of heat treatment. Heat treatment by preliminary ageing is carried out at conjugating base surface of the item with base surface of a heating plate. Preliminary ageing treatment is performed outside furnace. The item out of aluminium alloy and the heating plate are conjugated by placing a protective layer between the item out of aluminium alloy and the heating plate. The protective layer is made out of insulating material chosen from a group including glass-cloth, ceramic, glass wool, mineral cotton and woven and not woven polymer material. Also here are disclosed the heating plate and the facility for implementation of heat treatment by preliminary ageing.

EFFECT: production of dispersed-strengthened aluminium alloy with properties required for its implementation.
