摘要
利用合金平衡处理与电子探针微区成分分析及定量金相分析技术测定了Ti-Al二元系α/γ相平衡成分,明确了(α+γ)相区结构.结果表明,在1300℃下不存在β与γ相的相平衡关系.该结论与McCulough等人利用高温X射线衍射的测定结果一致。
The (α+γ) two phase field structure and α/γ phase equilibrium of Ti Al binary system were studied by means of alloy equilibrium treatment,electron probe microanalysis (EPMA) and quantitative optical microscopy. The results show that β/γ phase equilibrium does not exist at 1300 ℃. The measured (α+γ) two phase field of Ti Al binary system agrees with the result of McCullough C et al ,who used high temperature X ray diffraction,but does not support the result of Murray.
