Creep property of high-temperature titanium alloys is one of the most important indexes to evaluate their high-temperature performance. The microstructure of titanium alloy materials plays a decisive role in creep resistance. Coarser the grains are and finer the secondary phase is, better is the creep property. Suitable hot deformation parameters, heat treatment processes and surface treatment techniques can be selected to acquire satisfactory microstructure, which can significantly increase the creep property of high-temperature titanium alloys. Adding alloying elements has a significant effect on the improvement of titanium alloy creep resistance. Alloying elements can change the morphology and phase content of high-temperature titanium alloy, thus affecting its creep property. The development direction of creep property of high-temperature titanium alloys is optimization of the type and content of alloying elements, selection of suitable processing conditions and application of appropriate heat treatment or surface treatment processes.

高温钛合金的蠕变性能是评估其高温性能的最重要指标之一。钛合金材料的微观结构在抗蠕变性中起决定性作用。晶粒越粗，第二相越细，蠕变性能越好。可以选择合适的热变形参数，热处理工艺和表面处理技术以获得令人满意的显微组织，这可以显着提高高温钛合金的蠕变性能。添加合金元素对改善钛合金的抗蠕变性具有显著作用。合金元素会改变高温钛合金的形态和相含量，从而影响其蠕变性能。
