摘要
采用金属型重力铸造法制备了不同Nd含量的Mg-6Al镁合金，研究了不同成分镁合金的微观组织和性能。结果表明：添加稀土Nd能明显细化α（Mg）和β（Mg17Al12），产生新相Al11Nd3；随Nd含量的增加，合金硬度、抗拉强度和伸长率都得到明显提高。
Abstract：Mg-6Al alloys with different content of Nd were prepared by casting. The microstructure and properties of magnesium alloys were analyzed. The results show that： the addition of Nd into magnesium alloy can refine primary α（Mg） matrix and β （Mg17TAl12） phase. The addition of Nd forms Al11Nd3 phase. With the increase of Nd content, the hardness, tensile strength and elongation of the alloy increase rapidly.
