Progress in Microstructure Evolution during Power Spinning Process of Thin-walled Tube

The power spinning process of the thin-walled tube with hard-deforming materials is a complicated forming process with interaction of many factors,such as multi-fields,multi-factors and multi-passes.So,in the spinning process,the material of the tube undergoes a complex evolution process of microstructures.And microstructures of the spun tubes can determine their service performance.Thus,to understand the microstructure evolution mechanism and control of thin-walled hard-deforming material tubes in power spinning process,it is of great significance for realizing integrated control of forming shape and performance of this type of tubes during the process.Therefore,the progress in microstructure evolution of the hard-material thin-walled tube in power spinning process was reviewed from the aspects of experiment,micro-marco scale simulation and defects analysis,and its research problems and the development trend were prospected.
