Abstract

Abstract

In this study, subsequent solution heat treatment was carried out in order to improve the properties of high nitrogen nickel-free austenitic (HNNFA) stainless steel prepared by MIM. The effects of solution temperature and duration on the microstructures and mechanical properties of HNNFA stainless steel were systematically studied. In addition, the corrosion resistances of stainless steel specimens before and after solution treatment were compared. The results show that Cr₂N precipitates in the austenitic matrix after sintering, thus affecting the mechanical and corrosion resistance of the HNNFA stainless steel. The secondary phase of Cr₂N disappears after solution heat treatment and the microstructure is composed of pure austenite. When the solution temperature is 1 150 ℃ and the holding time is 10 min, the HNNFA stainless steel has the best mechanical properties. Its tensile strength reaches 889 MPa and elongation reaches 16.8%. Compared with the specimens before solid solution treatment, the corrosion rating of HNNFA stainless steel after solution treatment is increased from 0 to 10, and the corrosion resistance is greatly improved.
