Abstract The ban by the Federal Aviation Administration (FAA) of application of magnesium in aircraft cabins was lifted under the condition that the used materials have to fulfill the requirements for the ignition tests. This work proposes the novel Mg-2Y-2Gd-1Ca alloy with a small amount of Y, Gd and Ca as main alloying elements. Superior ignition temperature of 1100 °C was determined for this alloy. Analysis of the oxide layers revealed the presence of Y2O3, CaO, Gd2O3, and MgO in oxide layers which were observed to significantly suppress ignition compared to the pure Mg.

具有高着火温度和抑制可燃性的新型飞机 Mg-Y-Gd-Ca 合金

摘要 在所用材料必须满足点火测试要求的条件下，美国联邦航空管理局（FAA）取消了镁在飞机客舱中应用的禁令。这项工作提出了一种以少量 Y、Gd 和 Ca 作为主要合金元素的新型 Mg-2Y-2Gd-1Ca 合金。该合金的优越着火温度为 1100 °C。对氧化物层的分析表明，与纯 Mg 相比，氧化物层中存在 Y2O3、CaO、Gd2O3 和 MgO，它们被观察到显着抑制着火。
