“…Therefore, for recovery of samarium the discharge of Sm(III) on the reactive cathodes with the formation of intermetallic compounds is used. There are a lot of studies on the recovery of samarium with utilization of different cathodes from Cu, 9 Mg, 10,11 Zn,, 12,13 Cd, 14,15 Al, [16][17][18][19][20] Ga, 21,22 Sn,, 23 Bi, 14,15,24,25 Fe, 26,27 Co, [28][29][30] Ni. [30][31][32][33] At the same time, the number of studies devoted to the behavior of the Sm(III)/Sm(II) redox couple is small.…”

The electrochemical behavour of samarium in NaCl-KCl, KCl and CsCl melts have been studied in the temperature range 973–1173 K by different electrochemical methods. The diffusion coefficients (D) of Sm(III) and Sm(II) have been determined by linear sweep voltammetry, chronopotentiometry and chronoamperometry methods. The standard rate constants of charge transfer (k s) for the Sm(III)/Sm(II) redox couple have been calculated on the basis of cyclic voltammetry data using Nicholson’s equation. The nature of working electrode on the standard rate constants of charge transfer for the Sm(III)/Sm(II) redox couple has been studied. The formal redox potentials E * Sm(III)/Sm(II) have been obtained in alkali chloride melts from the cyclic voltammetry data.

“…Zhang et al [130][131][132][133] have also prepared Mg-Li-RE (Y, Sm and Er) alloys from RECl 3 /K 3 RECl 6 in the LiCl-KCl-MgCl 2 melts. Figure 38 shows the CVs of the LiCl-KCl melts before and after the addition of MgCl 2 and SmCl 3 on molybdenum electrodes at 903 K. The dotted line corresponds to a CV of the LiCl-KCl melts in the absence of MgCl 2 and SmCl 3 .…”

Magnesium-lithium base alloy is one of the lightest metallic engineering materials with a density of 1?35-1?65 g cm 23 , which is referred to as superlight materials. It has become an attractive material in the fields of aerospace, automobiles, portable electronics, etc. In this paper, the developing history and recent progress of superlight magnesium-lithium base alloys are reviewed. The progress on molten electrolysis preparation, processing technologies and surface processing technologies are introduced, and future research directions are suggested based on the current research progress.

“…[2,3] Nowadays, Mg-Li alloys are still drawing increasing academic and experimental interests for their good performances and potential use as components of automobiles and portable electronic devices. Recently, interests have focused on various aspects, such as preparing Mg-Li alloys by electrolysis in molten salt [4][5][6][7][8][9][10][11][12][13][14] and noncrystalline bulk Mg-Li alloys by rapid quenching, [15] developing new Mg-Li alloys through ab initio calculations, [16][17][18][19] characterizing Mg-Li alloys with the electron backscatter diffraction (EBSD) method, [20][21][22][23] improving mechanical properties via using severe plastic deformation (SPD) such as equal channel angle extrusion (ECAE), [24,25] among others.…”

Mg-8.43Li-0.353Ymm (Y-riched mischmetch) alloy was prepared using the metal model casting method and then hot-rolled at 573 K (300°C) to total reduction of 81 pct, and microstructures and mechanical properties were evaluated. Results show that the rolling procedure introduces great dynamic recrystallization, and b-Li grains in the rolled alloy present an ultra-low average size of 2.18 lm. The ultimate tensile strength and yield strength of the rolled alloy are 158-167 MPa and 124-130 MPa, respectively, 42-63 pct higher than that of the as-cast alloy. The elongation of the rolled alloy is improved to 31-40 pct, as about four to five times that of the as-cast alloy, which is ascribed to the great grain refinement of the b-Li phase.
