利用Pandat软件计算了Ti-Al-Nb三元系相图的等温截面、液相投影以及Ti-46.5Al-16.5Nb合金的相变。通过显微组织观察和热分析（TA）验证了合金的凝固顺序和随后的相变。用电子探针分析（EPMA）确定了1300 °C时α + β + γ三相区的三角形和1400 °C时α相和β相的连接线。在1300 °C下的α、β和γ相的相平衡以及在1400 °C下的α和β相的连接线都与文献中报道的计算相图不一致。确定了该合金的凝固顺序及随后的固态相变为：液相→液相+ β → β → α + β → α + β + γ → β + γ（本文未区分β相和B2相）。用差示扫描量热法（DSC）测定了样品的相变温度。
The isothermal sections of the phase diagram and the liquid projection of the Ti-Al-Nb ternary system as well as the phase transformations of a Ti-46.5Al-16.5Nb alloy were calculated using Pandat software. The solidification sequence and subsequent phase transformations of the alloy were verified by microstructural observations and thermo-analysis (TA). The tie-triangle of the three-phase region of α + β + γ at 1300 °C and the tie line of the α and β phases at 1400 °C were identified using electron probe microanalysis (EPMA). Neither the phase equilibria of the α, β and γ phases at 1300 °C nor the tie line of the α and β phases at 1400 °C are in agreement with the calculated phase diagrams reported in the literature. The solidification sequence and subsequent solid-state phase transformations of this alloy were determined as follows: liquid → liquid + β → β → α + β → α + β + γ → β + γ (The β phase and the B2 phase were not differentiated in the present paper.) The phase transformation temperatures were also measured by differential scanning calorimetry (DSC).
