It is an advanced plastic forming technology urgently needed to be researched and developed to solve the problem of forming high-performance light-weight components for aerospace. Achieving Formative Integrated Manufacturing is not only the key to meeting the demanding service performance of components in practical engineering fields, but also the major trend of development and research and development of high-performance lightweight components. The decisive role of microstructure on performance makes it an important issue that needs to be solved in order to control the organization of the development and application of the forming process. However, local loading is a highly nonlinear and complex physical process under multi-mold, multi-parameter and multi-field coupling, which makes microscopic
