摘要/Abstract

摘要： 以316L不锈钢为基础,设计并采用高压熔炼-高压凝固方法制备了氮含量为1.1%的高氮不锈钢钢,对其进行1050 ℃×10 h固溶处理及不同温度(600、800、1000 ℃)时效处理后,通过氮含量分布检测、组织观察、能谱扫描、力学性能测试、浸泡腐蚀、电化学腐蚀等方法,研究了高氮不锈钢铸锭氮含量分布以及固溶-时效处理后该高氮不锈钢的力学性能、耐蚀性能。结果表明,试验高氮不锈钢宏观氮含量分布均匀,但微观上存在N、Cr元素的富集,针状马氏体条带上的富集可以提高材料耐蚀性,氮化铬析出可以提高材料的强度但降低其耐蚀性;800 ℃时效2 h后,试验钢的力学性能最好,抗拉强度为771 MPa、屈服强度为658 MPa;固溶处理后的耐蚀性最好,800 ℃时效2 h试验钢相比其他时效温度处理的耐蚀性更好。综合力学性能及耐蚀性能,该高氮不锈钢的最佳热处理工艺为固溶处理后再进行800 ℃时效处理2 h。

Abstract: Based on 316L stainless steel, a high nitrogen stainless steel with nitrogen content of 1.1% was designed and prepared by high pressure melting and high pressure solidification method. After solution treatment at 1050 ℃ for 10 h and aging at different temperatures (600, 800 and 1000 ℃), the distribution of nitrogen content in the high nitrogen steel ingot and the mechanical properties and corrosion resistance of the high nitrogen steel after solution-aging treatment were studied by means of nitrogen content distribution detection, microstructure observation, energy spectrum scanning, mechanical properties test, immersion corrosion and electrochemical corrosion. The results show that the macro nitrogen content of the tested high nitrogen steel is evenly distributed, but the enrichment of N and Cr elements exists in the micro level. The enrichment on the acicular martensite strip can improve the corrosion resistance of the material, and the precipitation of chromium nitride can improve the strength of the material but reduce its corrosion resistance. The mechanical properties of the steel aged at 800 ℃ for 2 h are the best, with tensile strength of 771 MPa and yield strength of 658 MPa. The corrosion resistance of the steel after solution treatment is the best, and the corrosion resistance of the steel aged at 800 ℃ for 2 h is better than that of other aging temperature treatments. Comprehensively considering the mechanical properties and corrosion resistance, The optimum heat treatment process of the tested high nitrogen steel is the solution treatment followed by aging treatment at 800 ℃ for 2 h.

Key words: high nitrogen stainless steel, aging treatment, microstructure, mechanical properties, corrosion resistance
