The Al-Sr phase diagram in [Massalski2] was adopted from [1989Alc]. Although the overall phase diagram well represented numerous scattered experimental data, the liquidus of the Al2Sr phase appeared to be too pointed at the congruent melting point. This phase diagram was thermodynamically ...

The Al-Mg-Sr ternary phase diagram was calculated from the optimized thermodynamic properties of the binary systems. Since no reliable ternary data were available, three assumptions were made: no ternary terms were added to the model parameters for the thermodynamic properties of the liquid, no ...
Magnetization measurements of La0.5Sr0.5Mn1x Al x O3 (0≤x≤0.25) under pulsed high magnetic fields up to 50 T have been carried out, in which the Al3+ ions doping and magnetic field effects on the charge-ordering/antiferromagnetic to ferromagnetic phase transitions have been discussed. A ...

The phase diagram was determined in the complete composition range. Large ternary solubilities were found for the binary phases CaMg{sub 2}, Al{sub 2}Ca and Al{sub 3}Ca{sub 8}. Microstructures of samples with compositions near the ternary monovariant eutectic L {yields} CaMg{sub 2} + ...
Right: Phase diagram of Al-5.3Ni-xSr, with Sr varying from 0-1%. 2. Methodology Three compositions, Al-5.3Ni, Al-5.3Ni-0.015 Sr, and Al-5.3Ni-0.03 Sr were investigated. The Al-5.3Ni master alloy was created by melting and alloying AA196 and 99.97% pure Ni (nominal compositions ...
Calculated phase diagram sections and the liquidus surface together with thermodynamic equilibrium and non-equilibrium Scheil calculations of selected alloys are used to demonstrate the good agreement with all of the experimental microstructures. This provides additional support for the thermodynamic description...
Given the extensive alloy space in the Mg–Al–Sr system, thermodynamic calculations were employed to model the partial isothermal section phase diagram of the Mg–Al–Sr ternary system at 450°C. This model was validated by comparing its predictions with literature and experimental data, showing ...
Near UV-light excitable inorganic phosphors are widely recommended for white-light emitting diode (wLED) applications. Here in this paper we prepared Eu3+ doped SrAl2O4 phosphors with various concentrations of Eu3+ (1–5 mol%) by a green combustion technique. The phase structure and purity of...
