Abstract: The current assisted forming of Ti₂AlNb, a material difficult to deform, is a forming method developed in recent years. The current assisted flexible medium forming mold was designed, and it adopted ceramic split concave dies, and the metal part was made of 304 stainless steel. The mold was used to form Ti₂AlNb box part. The auxiliary pulse DC power duty cycle was 75%, step loading current was adopted, the final loading current was 300 A, the loading voltage was 3.12 V.The results show that with the decline of the punch, the flexible medium is filled and compacted at first, and then the middle part of Ti₂AlNb sheet begins to expand freely. With the continuous increase of forming force, the bottom is gradually contacted with the lower die, and the side walls and fillets are finally formed, the forming part has good quality. The quality of the forming part is good. The study can provide a process reference for current assisted flexible medium forming.
