Abstract: Taking Ti-22Al-25Nb alloy ring forgings as the object, the microstructure of the ring forgings with different deformation amounts was observed, the effects of deformation amount on the room temperature tensile property, room temperature notch sensitivity and high temperature tensile property were studied, and the fracture characteristics were analyzed. The results show that with the increase of deformation, the ratio of long axis to short axis of flattened B2 grains increases significantly, the content of primary lath O phase increases significantly, and the precipitated phases at grain boundaries become more discontinuous. The strength and elongation of the alloy increase with the increase of deformation amount. The ring specimen with 50% deformation amount achieves the best combination of strength and ductility. The grain boundary strengthening effect due to B2 grain size decrease and the discontinuity of precipitated phases at grain boundary are the main reasons for the increase of strength and ductility of the alloy. The tensile fracture at room temperature is mainly cleavage facet. With the increase of deformation, the secondary cracks on the tensile fracture at room temperature increase, and the ductile fracture characteristics increase.
