Review on Multi-pass Rolling Forming of Thin-walled Ring with Complex Section

Abstract

Abstract Superalloy thin-walled ring with complex cross section plays an important role in aerospace, energy and chemical industry, and it has excellent mechanical properties and oxidation resistance in high temperature and pressure environment. However, multi-pass rolling forming of thin-walled ring with complex cross-section of superalloy is a complex forming process that needs to undergo complex uneven plastic deformation under the coupling of multiple fields and factors. The research progress of multi-pass rolling forming of superalloy thin-walled ring with complex cross section is summarized from three aspects: deformation behavior and stress analysis, defect behavior analysis, process optimization and simulation, and several directions that need further research in the future are put forward.
