Development of bulk metallic glasses based on the Dy-Al binary eutectic composition罗林,田瑞,肖学山摘 要:<正>A series of dysprosium-based ternary, quadruple, and quintuple bulk metallic glasses (BMGs) based on Dy-Al binary eutectic compo-sition were obtained with the partial substitution of Co, Gd, and Ni elements, for dysprosium. The results showed......

) were separately used in the electrodeposition of Zn-Ni alloy films from a deep eutectic solvent. The effects of these two additives on electrodeposition behavior, composition, morphology, and corrosion performance of the Zn-Ni alloys were investigated. The electrodeposition behaviors of Zn-Ni alloy revealed by the cyclic voltammetry show that the addition of EDTA to the Zn-Ni electrolyte enhances......
. It was suggested that the microstructure evolution of the alloy during the solid solution treatment was concluded as follows: Mg5(GdEr) eutectic phase→Gd/Er atom diffusing into matrix→spheroidic Mg5(GdEr) phase→cuboid-shaped RE-rich phase→grain boundary immigration. Key words: Mg-Gd-Er-Zr alloy; microstructure evolution; solution solid treatment; eutectic phase 1 Introduction As a result......
