Effect of A Little Oxygen in Solid Solution on the Relative Stability Between α-Ti and β-Ti Phases
-
摘要: 本文利用Ti-O二元相圖及相關的熱化學數據計算了微量的固溶氧在α-Ti和β-Ti中對Ti活度系數的影響,并用獲得的活度系數分析了微量的固溶氧對α-Ti和β-Ti相對穩定性地影響,進而定性的解釋了不同實測Ti-Al相圖存在較大差異的原因。Abstract: The activity coefficient of Titanium in α-Ti and β-Ti phases were obtained from Ti-O binary phase diagram and some relative thermochemical data. Further, the effect of oxygen, which was quite a few amount and dissolved in Titanium, on the relative stability between α-Ti and β-Ti was discussed. The difference of Ti-Al binary phase diagrams among different author's experimental's was explained qualitatively.
