Covalent electron density analysis and surface energy calculation of gold with the empirical electron surface modelBao-qin Fu1,2),Zhi-lin Li1),and Wei Liu2) 1) College of Materials Science...,and the surface energy was calculated further.Calculation results show that CEDDB has a great influence on the surface energy of various index surfaces and the anisotropy of the surface.The calculated......
precipitation process. And the absolute value of solvation free energy reduces significantly in MgCl2 solution (1 mol/L) containing lithium ion. Key words: magnesium hydroxide; lithium; ammonia precipitation; interaction between ions; solvation free energy 1 Introduction Recently, extracting magnesium hydroxide has been the best way to utilize magnesium resources of natural brines [1-3]. The effects......
-Petch equation and free surface effect. Key words: micro-forming; micro-bending; size effects; free surface effect  ... the cross sectional area decreasing. Another reason is the free surface effect. For the existence of free surface layer, as shown in Fig.6, the flow stress decreases with the decrease of thickness[15......
microstructure. In the triple-layer core-shell microstructure, the surface layer is (Pb) phase, which is favourable to reducing the surface Gibbs free energy. EDS analyses reveal that both (Ni) and (Pb) phases..., the Maragnoni migration of the second liquid (Pb) phase was studied, which indicates that the L(Pb) phase droplets can migrate to the central part. Under free fall conditions, the cooling rate, surface......

and its deduction. Fig.3 Temperature dependence of surface tension of molten Ni-10%(Cr, Co, W) alloys: (a) Ni-10%Cr; (b) Ni-10%Co;(c) Ni-10%W The reasons for the difference are: 1) energy change of the system (mixing heat) not taken into account; 2) the measurement error; 3) the assumptions for a surface such as monolayer atom; 4) the differences in the energy of the Gibbs free energy......

and 550 °C, and the Si phase also has the possibility of melting. The main chemical reactions during thermal exposure are shown in Eqs. (3) and (4). The calculation results of the Gibbs free energy function under standard conditions are shown in Figure 10. It can be seen that the products of the two reactions are Al2O3 (three crystal structures) and SiO2. The Gibbs free energy increases......
