“…Table 4 collects data on the specific mass gains (mg/cm 2 ) for different alloys, including the examined AlNbTiVZr 0.25 alloy oxidized at 600–800 °C for 100 h in the air [30,31,50,58,59,60,61,62,63,64,65,66]. The mass gains of the AlNbTiVZr 0.25 alloy are comparable with some of the V-based alloys, namely V-30Al [59], Ti-based and TiAl-based alloys with a high V content like Ti-35.5V-14.6Cr-0.32Si-0.11C [62], Ti-15V-3Cr-3Sn-3Al [63], and Ti-42Al-8V-(2-4)Mo [50], and the TiZrNbHfTa RHEA [31]. Note that the Hf 0.5 Nb 0.5 Ta 0.5 Ti 1.5 Zr alloy suffered from even more severe oxidation due to pesting [29].…”

Oxidation behavior of a refractory AlNbTiVZr0.25 high-entropy alloy at 600–900 °C was investigated. At 600–700 °C, two-stage oxidation kinetics was found: Nearly parabolic oxidation (n = 0.46–0.48) at the first stage, transitioned to breakaway oxidation (n = 0.75–0.72) at the second stage. At 800 °C, the oxidation kinetics was nearly linear (n = 0.92) throughout the entire duration of testing. At 900 °C, the specimen disintegrated after 50 h of testing. The specific mass gains were estimated to be 7.2, 38.1, and 107.5, and 225.5 mg/cm2 at 600, 700, and 800 °C for 100 h, and 900 °C for 50 h, respectively. Phase compositions and morphology of the oxide scales were analyzed using X-ray diffraction (XRD) and scanning electron microscopy (SEM). It was shown that the surface layer at 600 °C consisted of the V2O5, VO2, TiO2, Nb2O5, and TiNb2O7 oxides. Meanwhile, the scale at 900 °C comprised of complex TiNb2O7, AlNbO4, and Nb2Zr6O17 oxides. The oxidation mechanisms operating at different temperatures were discussed and a comparison of oxidation characteristics with the other alloys was conducted.

“…Similarly, the work by Ba et al [11] examines the effect of silicon addition on both microstructure and tensile properties and provides an interesting read, as does the work by Chang on CP titanium [12]. Fretting and wear behaviour is an important application-based topic and is currently being actively researched in titanium alloys, as evidenced here by the papers by Mi et al [13] and He et al [14].…”

“…If the content of V is too high, it will inhibit the protection and density of Al2O3, thereby reducing the antioxidant properties of the Ti-Al-V alloys [11] . For instance, the depth of the oxidation layer of the Ti-35V alloy could be 1.45 times higher than that of Ti-25V alloy [12] . In addition, the activity of Al atoms in the Ti-Al-V alloy is raised with the decrease of the Ti content and the increase of the V content [13] .…”

For the issues of high temperature performance affected by the alloying elements content in Ti-V-Cr and Ti-V-Cr alloys, the thermodynamic calculation method based on JMatPro program was applied in this study. The research is mainly focused on the analysis of phase composition, thermodynamic parameters and mechanical properties of Ti-Al-V and Ti-V-Cr series alloys with different element proportions under high temperature environment. Those obtained results show that the proportion of Al in Ti-Al-V alloys has a great influence on the high temperature properties. Increasing the content of Al not only increases the transformation temperature of β single-phase structure and delays the transformation process of α/β microstructure to β single-phase structure, but also helps to improve the high temperature thermal conductivity and elastic deformation resistance of the alloy. In Ti-V-Cr alloys, the influence of V element on high temperature properties is mainly focused on the improvement of thermal conductivity and high temperature deformation properties, while the influence of Cr element is relatively weak. Besides, adding a small amount of Al element to Ti-V-Cr alloy can further improve the thermal conductivity of the alloy. The Young’s modulus of the Ti-V-Cr alloy increases when 0.3%-1% of C element is added. Finally, the effect of Si element on the high temperature elastic deformation of the alloy is relatively weak.
