(KO) 마그네슘 합금 판재, 및 그 제조방법
Abstract:
(EN) A method for manufacturing a magnesium alloy sheet According to one embodiment of the present invention comprises the steps of: casting molten metal comprising 2.7 to 5 wt % of Al, 0.75 to 1 wt % of Zn, 0.1 to 0.7 wt % of Ca, 1 wt % or less (0 wt % exclusive) of Mn, and a balance amount of Mg and inevitable impurities to prepare a casting material (S10); subjecting the casting material to homogenization heat treatment (S20); and warm rolling the homogenized casting material (S30).
(FR) Un procédé de fabrication d'une tôle en alliage de magnésium selon un mode de réalisation de la présente invention comprend les étapes consistant à : couler du métal en fusion comprenant entre 2,7 et 5 % en poids d'Al, 0,75 à 1 % en poids de Zn, 0,1 à 0,7 % en poids de Ca, 1 % en poids ou moins (0 % exclu) de Mn, et le reste étant Mg et des impuretés inévitables pour préparer un matériau de coulée (S10); soumission du matériau de coulée à un traitement thermique d'homogénéisation (S20); et laminage à chaud du matériau de coulée homogénéisé (S30).
(KO) 본 발명의 일 실시예에 의한 마그네슘 합금 판재의 제조 방법은 A1 : 2.7 내지 5 중량 %, Zn : 0.75 내지 1 중량 %, Ca : 0. 1 내지 0.7 중량 % 및 Mn : 1 중량 % 이하 (0 중량 %를 제외함)를 함유하고, 나머지는 Mg 및 불가피한 불순물로 이루어지는 용탕을 주조하여 주조재를' 제조하는 단계 (S10), 주조재를 균질화 열처리하는 단계 (S20) 및 균질화 처리된 주조재를 온간압연하는 단계 (S30)를 포함한다.
