采用磁控溅射法在硅片上制备了MgY和MgGd合金薄膜。采用扫描电镜（SEM）、透射电镜（TEM）、X射线衍射（XRD）和拉伸试验等手段对复合材料的微观结构、晶体结构和力学性能进行了分析。腐蚀进行了评估浸泡在3.5%NaCl溶液饱和Mg（OH）2。TEM、SEM和XRD表明合金为单相。腐蚀速率随合金含量的增加无明显变化。强度随合金含量的增加而增加，塑性随合金含量的增加而降低。强化与固溶强化或短程有序相一致。
Films of MgY and MgGd alloys were deposited on silicon wafers by magnetron sputtering. The microstructure, crystal structure and mechanical properties were evaluated using scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD) and tensile testing. Corrosion was evaluated for immersion in 3.5% NaCl solution saturated with Mg(OH)2. TEM, SEM and XRD indicated that the alloys were single phase. There was no significant change of corrosion rate with alloy content. The strength increased with alloying content, and ductility decreased concomitantly. Strengthening was consistent with solid solution strengthening or short-range order.
