“…The simulation or methods represented by SVM model [17] , neural network model [18] and thermodynamic model [19] can achieve efficient acquisition of microstructure and properties under different components, and provide an early basis for reducing the screening scope for test verification. For instance, the JMatPro program can not only directly obtain the hot-working microstructure phase diagram, CCT and TTT diagram [20] of different alloys, but also indirectly serve as the initial parameters [21] or comparison verification items of other numerical calculation programs [22] . Besides, it can also be used to optimize the alloy processing technology including heat treatment [23] .…”

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.
