and their Ti data base. Ti-Al and Ti-Al-V phase diagrams and the transition of α and β-phase and their thermodynamic stability from room-temperature (RT) to 1200 °C, under equilibrium conditions, were predicted... Kα radiation (λ=1.789 ). Phases were identified using X’Pert Highscore plus software. 3 Thermodynamic and experimental results The diagrams of formation and stability of phase in an equilibrium......
After annealing at 1000 °C for 30 d, the alloys reach the equilibrium. As can be seen from Tables 1-3, the composition of the precipitated B2 phase is 27.0-35.4 at.% Al, 3.1-6.4... C T. Phase selection in high-entropy alloys: From nonequilibrium to equilibrium [J]. JOM, 2014, 66(10): 1966-1972. [20] SUN Ya, WU Chang-jun, LIU Ya, PENG Hao-ping, SU Xu-ping. Impact of alloying......
experiments indicate that the composition of spinel in equilibrium with the liquid phase approaches the franklinite composition (ZnFe2O4) in air in the range of temperatures investigated. The sample... Trans. Nonferrous Met. Soc. China 22(2012) 665-674 Effect of CaO/SiO2 and Fe/SiO2 ratios on phase equilibria in PbO-ZnO-CaO-SiO2-"Fe2O3" system in air M. PEREZ-LABRA1, A.

, and the maximum solubility is 3.0%Zn, more than that of Mg-Zn binary system (2.1%Zn) when the α-Mg solid solution is in equilibrium with the liquid phase. However, the solubility of Al in the α-Mg phase decreases due to the addition of Zn when the α-Mg phase is in equilibrium with the γ intermetallic compound, i.e., the Al solubility is 7.8% in the Mg-Al binary system, decreasing to 5.2%. At the same time......

that Mg2Si is a plate-like or block-shaped phase, and Si particles often present as binary eutectic with Mg2Si, as shown in Fig.2(a). Fe has a very low solid solubility in Al (maximum 0.05% at equilibrium... electron microscope(SEM), transmission electron microscope(TEM) and tensile tester. The results indicate that the phase constituents in the as-cast microstructure are Mg2Si, Si, Al5Cu2Mg8Si6, Al5FeSi......
. The Gibbs energies of face-centred cubic and liquid phases were described by a sub-regular solution model with the Redlich-Kister equation. Much effort was taken to reproduce the phase equilibrium... differences from our recent phase equilibrium data using the diffusion couple technique [20]. Later, GROLIER and RAINER [18] re-assessed the Au-Pt system using simple sub-regular solution model to the liquid......
