based on the one-dimensional electrochemical model. The results show that both liquid phase and solid phase diffusion polarizations exist in the positive and negative electrodes, and diffusion polarization increase with the conducting of the discharge process. The particle size of active materials has a distinct impact on the solid phase diffusion polarization, reducing the active material particle......
Fluoride solid electrolytes containing rare earth elementsViera Trnovcová,Pavel P. Fedorov,Ivan Furár1摘 要:Relations between the structure, ionic... orthorhombic fluoride phases (GdF3, SmF3), which cannot be prepared as single crystals. An influence of the orthorhom- bic-tysonite phase transition on the ionic conductivity was shown.关键词:......
of the limitations of solid metal heat sink in the heat dissipation of high power light emitting diode (LED), a kind of miniaturized phase change heat sink is developed for high power LED packaging... transfer performance is investigated. Finally, the heat transfer performance of the developed miniaturized phase change heat sink is compared with that of metal solid heat sink. Results show......
Interfacial Reaction Between Solid Nickel and Liquid Zinc孔纲School of Materials Science and Engineering, South China University of Technology摘 要:Interfacial reactions between solid nickel and liquid zinc at 450-650 ℃ for 30-600 s were studied. The morphology and growth behavior of intermetallic compound layers at the interface between solid nickel......

Tensile fracture of as-cast and hot rolled Mg-Zn-Y alloy with long-period stacking phase WANG Bai-shu(王柏树)1, 2, XIONG Shou-mei(熊守美)1, LIU Yong-bing(刘勇兵)3 1. State Key Laboratory of Automotive... (LPS) phase. Tensile tests of Mg97Zn1Y2 alloy in comparison with pure Mg were conducted. The fracture morphologies of the tensile specimens were characterized and the microstructures near fracture......
temperature and composition. In this section, only the solid-state phase equilibria at 1 350 ℃ and liquid-solid phase equilibria for selected alloys are shown, and their use in the validation of the calculated results is described. 2.2.1 Solid-state phase equilibria at 1 350 ℃ in Nb-rich region Fig.1 shows the calculated isothermal sections of the Nb-Cr-Ti-Si system at 1 350 ℃ with the Cr content being......
] and solid-liquid interface in pure metals [8]. In the last several years, the quantitative phase field method has been well established and widely applied to studying the phase transformation kinetics... of interface mobility was given and the phase-field mobility was calibrated accordingly. In the case of solidification, under the assumptions of negligible diffusivity in solid and constant diffusivity within......
