Abstract: S32760 duplex stainless steel (DSS) is widely used in marine engineering and chemical equipment owing to its excellent strength and corrosion resistance. The severe plastic deformation and thermal effects induced by machining cause significant evolution of the microstructure in the machined surface layer. Grain size is a key parameter characterizing the microstructure, and its variation affects the service performance of the material. Owing to the distinct deformation mechanisms of the dual-phase grains in duplex stainless steel, microstructural evolution during cutting is more complex to characterize. In this study, a grain-size prediction subroutine based on dislocation density evolution was developed by combining EBSD experiments and finite element numerical simulations. The effects of cutting parameters (cutting speed, feed rate, and tool rake angle) on the evolution of grain size and dislocation density in the two phases were investigated. The results indicate that the proposed model can characterize two-phase grain-size evolution; grain refinement is generally. Cutting speed and feed rate are the main process parameters affecting grain refinement, while the tool rake angle has no significant effect. The recommended parameter combination considering grain refinement and cutting stability is cutting speed 300 m/min, feed rate 0.08 mm/r, tool rake angle 12°. This research explores the underlying mechanism associated with grain-size modification during duplex stainless steel machining operations. Such knowledge is crucial for advancing the surface quality and service life reliability of S32760 duplex stainless steel components. [ABSTRACT FROM AUTHOR]
