Simple shear extrusion versus equal channel angular pressing:A comparative study on the microstructure and mechanical properties of an Mg alloy

Journal of Magnesium and Alloys 2023年第5期11卷 1769-1790页

Two severe plastic deformation(SPD)techniques of simple shear extrusion(SSe)and equal channel angular pressing(eCAP)were employed to process an extruded Mg-6Gd-3Y-1.5Ag(wt%)alloy at 553 K for 1,2,4 and 6 *** microstructural evolutions were studied by electron back scattered diffraction(eBSD)analysis and transmission electron microscopy(TeM).The initial grain size of 7.5μm in the extruded alloy was reduced to about 1.3μm after 6 SPD *** dynamic recrystallization was suggested to be operative in both SSe and eCAP,with also a potential contribution of continuous dynamic recrystallization at the early stages of *** difference in the shear strain paths of the two SPD techniques caused different progression rate of dynamic recrystallization(DRX),so that the alloys processed by eCAP exhibited higher fractions of recrystallization and high angle grain boundaries(HAGBs).It was revealed that crystallographic texture was also significantly influenced by the difference in the strain paths of the two SPD methods,where dissimilar basal plane texture components were *** compression tests,performed along extrusion direction(eD),indicated that the compressive yield stress(CYS)and ultimate compressive strength(UCS)of the alloys after both See and eCAP augmented continuously by increasing the number of ***-processed alloys had lower values of CYS and UCS compared to their counterparts processed by *** difference in the mechanical responses was attributed to the different configurations of basal planes with respect to the loading direction(eD)of each SPD technique.

Advanced Polymer electrolytes for High-energy-density Power Sources

引用

复旦学报（自然科学版） 2005年第5期44卷 670-671页

作者： D. Golodnitsky e. Livshits R. Kovarsky e. Peled School of Chemistry Tel Aviv UniversityTel Aviv 69978Israel

The preparation of highly controlled thin films of lithium ion conducting organic materials is becoming a challenging but rewarding goal in view of obtaining high-performance technological devices like solid-state polymer batteries and capacitors. The classical polymer electrolyte consists of organic macromolecules (usually polyether polymer) that are doped with inorganic (typically lithium) salts. Poly(ethylene oxide) (PeO) is the most commonly employed polymer in Pes because of the peculiar array in the (-CH2-CH2-O-)n chain providing the ability to solvate low-lattice-energy lithium salts. For three decades the major research attention was focused on amorphous polymer electrolytes in the belief that ionic conductivity occurs in a manner somewhat analogous to gas diffusion through polymer membranes. Segmental motion of the polymer chains continuously creates free volume, into which the ions migrate, and this process allows ions to progress across the electrolyte. Such a view was established by a number of experiments, and denied the possibility of ionic conductivity in crystalline polymer phases. This concept has been recently overturned by our group, demonstrating that conductivity comes about as a result of permanent conducting pathways for the movement of ions.
