Title (EN) 7XXX SERIES ALUMINUM ALLOY PRODUCTS IN A STABILIZED T4 TEMPER AND METHODS OF MAKING THE SAME
(FR) PRODUITS EN ALLIAGE D'ALUMINIUM DE SÉRIE 7XXX DANS UN ÉTAT DE REVENU T4 STABILISÉ ET LEURS PROCÉDÉS DE FABRICATION
Abstract:
(EN) The present disclosure generally provides 7xxx series aluminum alloy products in a stable T4 temper. The disclosure also provides methods of making such products, for example, using processes that include a combination of casting, rolling, solutionizing, quenching, reheating, and slow cooling. The disclosure also provides various end uses of such products, such as in automotive, transportation, electronics, and industrial applications.
(FR) La présente invention concerne d'une manière générale des produits en alliage d'aluminium de série 7xxx dans un état de revenu T4 stable. L'invention concerne également des procédés de fabrication de tels produits, par exemple, à l'aide de procédés qui comprennent une combinaison de moulage, de laminage, de mise en solution, de trempe, de réchauffage et de refroidissement lent. L'invention concerne en outre diverses utilisations finales desdits produits, telles que dans des applications automobiles, de transport, électroniques, et industrielles.
