| 英文摘要 | The precipitation behavior of Cr-2 N during isothermal aging in the temperature range from 700 degrees C to 950 degrees C in Fe-18Cr-12Mn-0.48N (in mass percent) high nitrogen austenitic stainless Steel. including morphology and content of precipitate, was investigated using optical microscopy. Scanning electron Microscopy, and transmission electron microscopy. The isothermal precipitation kinetics curve of Cr-2 N and the corresponding precipitation activation energy were obtained. The results show that Cr-2 N phase precipitates in a cellular way and its morphology is transformed from initial granular precipitates to lamellar ones in the cell with increasing aging time. The nose temperature of Cr-2 N precipitation is about 800 degrees C. with a corresponding incubation period of 30 min, and the ceiling temperature of Cr-2 N precipitation is 950 degrees C. The diffusion activation energy of Cr-2 N precipitation is 296 kJ/mol. |
