主　　题：Buckling-induced forming Dieless No wall-thinning Stainless-steel bellows 

摘      要：A novel buckling-induced forming method is proposed to produce metal *** tube billet is firstly treated by local heating and cooling,and the axial loading is applied on both ends of the tube,then the buckling occurs at the designated position and forms a *** this paper,a forming apparatus is designed and developed to produce both discontinuous and continuous bellows of 304 stainless steel,and their characteristics are discussed ***,the influences of process parameters and geometric parameters on the final convolution profile are deeply studied based on FEM *** results suggest that the steel bellows fabricated by the presented buckling-induced forming method have a uniform shape and no obvious reduction of wall ***,the forming force required in the process is quite small.
