Title (EN) HIGH-STRENGTH ALUMINUM ALLOY PLATE HAVING EXCELLENT PAINT BAKE HARDENABILITY, AND MANUFACTURING METHOD THEREFOR
(FR) PLAQUE D'ALLIAGE D'ALUMINIUM À HAUTE RÉSISTANCE AYANT UNE EXCELLENTE TREMPABILITÉ DE CUISSON DE PEINTURE, ET SON PROCÉDÉ DE FABRICATION
(KO) 소부경화성이 우수한 고강도 알루미늄 합금 판재 및 이의 제조방법
Abstract: front page image
(EN) The present invention relates to a high-strength aluminum alloy plate having excellent paint bake hardenability, and a manufacturing method therefor, and by performing a preliminary aging treatment for 3-250 minutes at a temperature of 65-145°C after solution heat treatment during the manufacture of a plate, a physical property change due to natural aging during transport and storage of the plate is suppressed, and the strength of the plate can be further improved by paint bake-hardening after chassis molding and painting, thereby having an advantage of enabling a high-strength lightweight transport vehicle chassis to be manufactured.
(FR) La présente invention concerne une plaque d'alliage d'aluminium à haute résistance ayant une excellente trempabilité de cuisson de peinture, et son procédé de fabrication, et par la réalisation d'un traitement de vieillissement préliminaire pendant 3-250 minutes à une température de 65-145 °C après un traitement thermique de solution pendant la fabrication d'une plaque, un changement de propriété physique dû au vieillissement naturel pendant le transport et le stockage de la plaque est supprimé, et la résistance de la plaque peut être encore amélioré par durcissement de cuisson de peinture après moulage de châssis et peinture, ce qui a pour avantage de permettre la fabrication d'un châssis de véhicule de transport léger à haute résistance.
(KO) 본 발명은 소부경화성이 우수한 고강도 알루미늄 합금 판재 및 이의 제조방법에 관한 것으로, 판재 제조시 용체화 처리 이후 65 내지 145 ℃의 온도에서 3 내지 250분 동안 예비 시효처리를 수행함으로써, 판재의 이송 및 보관 중의 자연시효로 인한 물성변화를 억제하고 차체 성형 및 도장 후 소부경화에 의해 강도를 더욱 향상시킬 수 있어, 고강도를 갖는 경량 수송기기 차체를 제조할 수 있는 장점이 있다.
