摘      要：This study aims at investigating the impact of using the Magnetorheological Elastomers(MREs)medium to improve the formability of T-shaped Inconel 718 tubes during the bulging ***,the influence of the punch size and the intensity of the magnetic field on the branch height and wall thickness distribution of the T-shaped Inconel 718 tubes are also *** results showed that the parts formed by the punch with a length of 5 mm in the pressurization zone have better forming *** external magnetic field can promote a high branch,and by increasing the intensity of the magnetic field,the branch height was increased and then *** the same time,the magnetic field reduced the amount of material accumulation between the guiding zone and the bulging ***,it promotes the material in the guiding zone to enter the bulging zone and improve the bulging ability of the T-shaped tube.
