“…Figure 7 is the enlarged part concerning the reaction (βY) + L = (αY). Though less number of the adjustable parameters was adopted in the present work, a better reproduction of the experimental data was attained in comparison with the previous calculations [11,12]. According to the present calculation, a peritectic reaction of (βY) + L = (αY) occurs at 1481 °C, which is in accord with Love [3].…”

“…They suggested that (βY) cannot be described with a simple regular solution model [9]. Later on, the Zr-Y system was thermodynamically optimized by Flandorfer et al [11] and He and Liu [12] using CALPHAD method. Due to the limited experimental information, the thermodynamic parameters for the individual phases in the Zr-Y system were evaluated by using the trial and error method.…”

Based on the critical review of all the available experimental data in the literature, 8 key alloys were prepared by arc melting to investigate the phase equilibria in the Zr-Y system, These alloys, which were annealed at 5 different temperatures (800°C, 1000°C, 1100°C, 1120°C, 1160°C), were analyzed by means of X-ray diffraction, differential scanning calorimetry, optical microscopy and scanning electron microscopy with energy-dispersive X-ray spectroscopy. The results showed that a peritectoid reaction (βZr) + (αY) = (αZr) occurs at 886°C ± 5°C, and an eutectic reaction L = (βZr) + (αY) occurs at 1313°C ± 5°C. Taking into account the experimental data obtained both from this work and the literature, the Zr-Y system was thermodynamically modeled. The previously reported temperature for the peritectic reaction of (βY) + L = (αY) at about 1490 °C is supported by our thermodynamic calculation. Comparison between the calculated and measured phase diagrams shows that the thermodynamic calculation can well account for the experimental data

“…The thermodynamic description was then applied to construct database of the Cu-Y-Zr system by He and Liu [30] with a minor modification on the parameters. The parameters presented by He and Liu [30] could give more accurate description in the high temperature region of the Y-Zr system and were applied in the present work. Consequently, the thermodynamic parameters taken from the Mg-Y [26], Mg-Zr [28], and Y-Zr [30] binary systems are used for comparison between the calculations and experimental data.…”

The Mg-Y-Zr system was studied via experimental investigation and thermodynamic modeling. Four diffusion couples and four key alloys of the Mg-Y-Zr system at 500°C were prepared. The phase relations of the Mg-Y-Zr system were investigated by means of X-ray diffraction, scanning electron microscopy, and electron probe microanalysis. No ternary compound was found at 500°C. The solubility of (aZr) in the Mg-Y intermetallics, i.e., Mg 24 Y 5 , Mg 2 Y and MgY, was determined to be negligible. The differential scanning calorimetry measurement was performed on the Mg-Y-Zr alloys to obtain the phase transition temperature. The present thermodynamic calculations of the Mg-Y-Zr system matched well with the experimental data. The presently established Mg-Y-Zr phase diagram can offer a better understanding of the recent processing technique of creep-resistant magnesium alloys.
