Trans. Nonferrous Met. Soc. China 23(2013) 3104-3111 Effect of oxide and fluoride addition on electrolytic preparation of Mg-La alloy in chloride molten salt Shi-dong WANG1,2, Quan LI1, Xiu-shen YE1... diffraction (XRD) was used to characterize some of the Mg-La alloy products and the sludges. As the content of MgO or La2O3 in the electrolyte increased, both the current efficiency and the mass of alloy......
, 2.4 mm/a in a 3.5 wt.% NaCl solution, Furthermore, the discharge performance of Mg-0.4La alloy was superior to that of pure Mg and other Mg-La alloys; this could be associated with the modified microstructure of the Mg-0.4La alloy, which decreased the self-corrosion and accelerated the detachment of the discharge products. Key words: Mg-based batteries; Mg-La alloys; corrosion rate; discharge......
电解质组成对氯化物体系熔盐电解Mg-La合金的影响(英文)王世栋1,2,李权1,叶秀深1,孙庆国1,吴志坚11. 中国科学院青海盐湖研究所盐湖与资源化学重点实验室2. 中国科学院大学摘 要:在Mg Cl2-La Cl3-KCl熔盐体系中,系统研究了恒电位电解过程中,电解质组成对平均电解电流,电解效率和合金成分的影响.用XRD,SEM和EDS对Mg-La合金样品进行了表征.随着初始电解质中La Cl3浓度的增加,平均电解电流逐渐降低.这是由于与Mg Cl2相比,La Cl3较低的电导率引起的.当La Cl3在初始电解质中的浓度为15%20%(质量分数)时,电流效率超过90%.合金组成可通过改变电解质组成来调节.关键词:Mg-La合金;熔盐电解;共电沉积;电流效率;......
Mg-La和Mg-Nd二元合金相稳定性的第一原理研究张会,王绍青中国科学院金属研究所沈阳材料科学国家(联合)实验室摘 要:La和Nd是镁合金中常用的稀土添加元素,为了帮助理解它们在Mg合金中的强化机制,应用第一原理计算方法,研究了Mg-La和Mg-Nd二元合金的相稳定性.计算结果表明,Mg-La和Mg-Nd合金在Mg12RE和Mg3RE之间的平衡相分别为Mg17La2和Mg41Nd5;La和Nd在Mg中的溶解度大小差别较大,表明者在镁合金中产生强化的机理不同;Mg3Nd具有比Mg12La更大的弹性模量,因而具有更好的强化效果.关键词:第一原理;镁合金;稀土元素;......
