| dc.description.abstract | Mg-4Li alloys with the addition of Al, Si, Y elements were prepared by vacuum melting and rolling process. The microstructure, electrochemical corrosion of the alloys are investigated. The results indicate that the grain size and the second phase are modulated with the addition of Al and Y elements compared with the Mg-4Li alloy, the corrosion resistance is enhanced significantly. However, the Si element is detrimental to corrosion resistance, attributing to the more negative potential of Mg2Si phase. The oxidation product primarily consist of Mg(OH)2 and Li2CO3, which protected the Mg-4Li-3Al-1Si-0.5Y alloy effectively. | ru |

| local.description.annotation | 通过真空熔炼和轧制工艺制备了添加了Al Si、Y 元素的轧制态Mg-4Li 合金。研究了 合金微观结构、静态腐蚀和电化学腐蚀等 面的区别。结果表明，随着Al 和Y 元素的加入， 通过细化晶粒和调控第二相。合金耐蚀性得到了显著提高。然而，Si 元素对腐蚀是 利的，这 归因于Mg2Si 相的电位较负，而Si 是以共晶相的形式存在。Mg-4Li-3Al-1Si-0.5Y 合金的平均腐 蚀速率为15.71mm/年。氧化产物膜主要由Mg(OH)2和Li2CO3组 ，有效地保护了基体。 | ru |
