Structure property regulation and control process for Ti2AlNb aero-engine case part

The invention discloses a structure property regulation and control process for Ti2AlNb aero-engine case parts, and belongs to the field of material heat treatment. The diameter size of the Ti2AlNb aero-engine case type part is generally not less than 500mm, the overall heat treatment of the Ti2AlNb aero-engine case type part can be realized by adopting the process, the case type part is put into a heat treatment furnace, the temperature of the part is increased to T1 along with the furnace, heat preservation is performed for a period of time, heating is stopped, and the part is cooled to room temperature and discharged out of the furnace; and then heat treatment at T2 temperature is carried out, so that the structure is more uniform, and the performance is more stable. According to the method, the mechanical property of the Ti2AlNb aero-engine case part can be improved, and the structure is more uniform. 本发明公开了一种Ti2AlNb航空发动机机匣类零件的组织性能调控工艺，属于材料热处理领域。Ti2AlNb航空发动机机匣类零件的直径尺寸一般不低于500mm，采用该工艺能够实现Ti2AlNb航空发动机机匣类零件的
