摘要
在分析10Cr18Ni9NbCu3BN奥氏体不锈钢显微组织的基础上,计算预测钢中未溶碳氮化物和高温铁素体δ相的含量和材料的强度,并分析热处理工艺的合理性.研究结果表明,高温铁素体δ相的计算值与试验结果相符;材料强度的计算值与试验结果相近;固溶处理温度可降低到1100℃;软化处理温度可降低到1150℃.对奥氏体不锈钢热处理工艺、组织和强度进行的计算分析将为企业生产提供重要的理论依据.
Based on the analysis of heat treatment process and microstructure of austenitic steel 10Cr18Ni9NbCu3BN, the amounts of carbide, nitride and δ phase of high temperature ferrite in steel are calculated and predicted. The analysis results show that the calculated amounts of δ phase and mechanical strength of the austenitie steel have good correspondence with the experimental values. Furthermore, the temperature of solution treatment can drop to 1 100 ℃ and the temperature of softening can drop to 1 150℃. In conclusion, this study provides theoretical foundation for the manufacture and heat treatment of austenitic steel.
