- Abstract
To refine the microstructure and improve the mechanical properties of the metal tubes, a new kind of severe plastic deformation process of the cyclic rotating bending (CRB) process was newly proposed. This study focused on the investigation of evolution of microstructure and mechanical properties of aluminum alloy (6061) tube in the CRB processes with different bending angles and deformation temperatures. The tensile test was employed to evaluate the mechanical properties of the tube after deformation, and Optical Microscopy were utilized for the microstructure characterizations. The results showed that the temperature and bending angle have a strong influence on the mechanical properties and microstructure of the specimens processed by the CRB process. As a result that the aluminum alloy (6061) tube with a grain size of 86 um as well as ultimate tensile strength of 244 MPa and total elongation of 10.05% was successfully obtained with the optimized deformation condition of the CRB process with a temperature of 100oC and bending angle of 170o, when the rotation speed and deformation time were fixed at 20rpm and 5min, respectively.
