| (57) Abstract: | ||
| (EN): The present invention addresses the problem of providing a magnesium alloy sheet that can be shaped at ordinary temperatures and has an excellent balance between strength and ductility. The aforementioned problem can be solved by a magnesium alloy sheet comprising, by mass%, 2.4-5.0% of Zn, 0.3-2.0% of Ca, 0.0% to less than 1.5% of Al, with the Zn/Ca ratio falling within a range satisfying 2.0 to 14.0,and the balance magnesium and inevitable impurities, or by a magnesium alloy sheet further containing 0.0% to less than 0.5% of Sn and/or 0.0% to less than 1.7% of Mn in addition to the aforementioned composition.
(FR): L'invention concerne une feuille d'alliage de magnésium pouvant être façonnée à des températures ordinaires et dotée d'un excellent équilibre entre la résistance et la ductilité. La feuille d'alliage de magnésium selon l'invention comprend, en % en masse, de 2,4 à 5,0 % de Zn, de 0,3 à 2,0 % de Ca, 0,0 % ou moins de 1,5 % d'Al, le rapport Zn/Ca se trouvant dans une plage allant de 2,0 à 14,0, et le reste étant constitué de magnésium et d'impuretés inévitables. La feuille d'alliage de magnésium selon l'invention peut également comprendre 0,0 % ou moins de 0,5 % de Sn et/ou 0,0 % ou moins de 1,7 % de Mn, en plus de la composition susmentionnée. (JA): 常温での成形が可能なマグネシウム合金板であって、優れた強度-延性バランスを有するマグネシウム合金板を提供することを課題とする。 質量％で、Ｚｎを２.４～５.０％、Ｃａを０.３～２.０％、Ａｌを０.０％以上１.５％未満含有し、かつＺｎ／Ｃａの比が２.０～１４.０を満足する範囲であり、残部がマグネシウム及び不可避的不純物からなるマグネシウム合金板、または、前記組成にさらにＳｎを０.０％以上０.５％未満、及び／あるいはＭｎを０.０％以上１.７％以下含有するマグネシウム合金板により上記課題は解決される。 |
