Abstract

Language:

Duplex stainless steels (DSS) combine remarkable mechanical properties with superior corrosion resistance, making them desirable for various applications. This study investigates the challenges associated with achieving a balanced microstructure of ferrite and austenite in DSS when processed using Laser Powder Bed Fusion (LPBF). The objective is to explore the impacts of post-processing techniques, specifically stress-relief annealing, on enhancing the mechanical and corrosion resistance properties of DSS. Through a series of experiments, we assess the microstructural changes resulting from different annealing parameters and their subsequent effects on polarization resistance and charge transfer resistance. The results reveal that solution-annealed Super Duplex Stainless Steel (SDSS) exhibits improved corrosion resistance, while stress-relief annealing at 300°C for 5 hours facilitates modest enhancements in electrochemical properties compared to as-printed samples. Additionally, it was found that the mechanical properties and microstructure of as-printed HDSS significantly improve upon post-processing. Future work will focus on optimizing time-temperature parameters for stress relief to further enhance the quality of LPBF-printed DSS components.
