“…These precipitates are randomly distributed within the micron‐sized RGs. The red circle in the figure represents the position of the electron diffraction pattern and the energy dispersive spectroscopy (EDS) energy spectrum, confirming that the precipitated phase is M 23 C 6 , which aligns with the findings of Liu et al [ 45 ] It is important to note that the content of Mo, Cr, and C in the precipitated phase slightly increases with the rise in aging temperature. According to Zhao et al, [ 46 ] thermodynamic calculations reveal that cold‐deformed ASS tends to form M 23 C 6 precipitates within the RG structures when annealed below ≈860 °C.…”

316L austenitic stainless steel (ASS) with a heterogeneous structure exhibits favorable mechanical properties at room temperature, promising excellent application potential. However, the thermal stability of 316L ASS with heterogeneous lamella structure (HLS) has not been adequately addressed yet. Herein, an HLS of 316L ASS is fabricated through 78% cold rolling followed by annealing at 750 °C for 13 min. The detailed investigation focuses on the influence of microstructure evolution on the mechanical properties and corrosion resistance of the alloy after aging at temperatures ranging from 350 to 550 °C for 100 h. The results show that a notable quantity of residual martensite persists even after annealing at high temperatures for a brief duration. The dislocation density of the test steel is reduced after long‐term aging treatment, and the residual martensite is further reversed into austenite during aging. In addition, the aging treatment also promotes further growth of nanocrystalline/ultrafine‐grained, which weakens the heterogeneous characteristics of HLS 316L ASS, resulting in a slight decrease in mechanical properties. However, the decrease in defect density and the enhancement of recrystallization degree are beneficial for eliminating most of the corrosion‐sensitive areas in the cold‐deformed structure, thereby improving the corrosion resistance.

“…The application of an external electric field as new technology has been used widely in the field of metallurgy because of its low energy consumption and the gain effect it brings to related processes [26][27][28][29][30][31] such as, refining, continuous casting, and heat treatment, etc. Meanwhile, based on the theory of slag ions, both the submerged entry nozzle and the mold flux can be regarded as "conductors" during the continuous casting procedure.…”

Considering the change and unpredictability of the mold flux containing rare earth oxides, the impact of controlling the erosion behavior of the mold flux containing rare earth oxide on the submerged entry nozzle is thoroughly investigated herein by applying an electric field. The extracted results show that the rare earth is reduced, and Ce 3þ ions and compounds are formed. Under the control of electrochemical reaction in the negative enforced electric field, a stable and dense protective film with a multilayer structure is formed on the surface of the electrode. The existence of this film can effectively prevent the erosion of the submerged entry nozzle. In addition, the phase composition of the mold flux is not affected by the externally applied electric field. The implementation of the external electric field is anticipated to be used as a new method for the highquality and high-efficiency continuous casting production of rare earth steel.
