Abstract: According to the product characteristics of large diameter thin-walled TA24 titanium alloy tube for a ship piping system, the medium frequency induction heating bending process test of φ426 mm×10 mm tube was carried out.The surface quality of the bending tube, wall thickness thinning ratio, and roundness of the cross-section were analyzed.Mechanical properties and metallographic structure under hot bending, 750℃heat treatment and 800℃heat treatment were studied.The results show that the given hot bending process parameters can be used to prepare TA24 alloy bending tube that meets the requirements.
