With the development of the aerospace field and advancement of science and technology,the application field of die-less spinning is becoming more and more extensive.Pre-formed workpieces can be obtained by spinning without a mandrel support,which can really achieve the purpose of high efficiency and low consumables.However,the lack of mandrel support makes it difficult to determine the direction and speed of metal flow of the original blank during forming process.The study of the formed workpiece microstructure can reflect the metal flow and plastic deformation on the macroscopic level,and it can also deeply reveal the related mechanism of the spin forming method.So far,there are few studies on the evolution of the microstructure of die-less spinning forming,which is summarized in this paper.According to the microanalysis of the influence of the spinning parameters on the forming accuracy; through the microstructure of the grain orientation and grain size of the spinning process to carry out a detailed analysis of the metal flow; according to the microstructural characteristics of the spinning workpiece can be the study of the mechanical properties,which helps to reveal the spinning process.The study of the mechanical properties of the spinning workpiece can help to reveal the forming mechanism of the spinning process.
