摘要
从工业化生产的0Cr19Ni9N大筒件实物中取样,研究了氮含量对大锻件力学性能的影响。用金相分析手段,分析了固溶处理工艺对锻件力学性能和显微组织的影响。结果表明,0Cr19Ni9N锻件可通过再结晶得到细小均匀的组织;随氮含量的提高,锻件的强度增加,塑性略有下降;氮含量从0.14%提高到0.20%时,锻件的屈服强度可增加30MPa,抗拉强度可增加50MPa。
The specimens were taken from a large forged 0Cr19Ni9N cylinder to investigate the effect of nitrogen content on mechanical properties of forging with the help of microscopical examination. Meanwhile, the effect of solid solution process on mechanical properties and microstructure of forging was also studied. It was shown that the microstructure of forging is finer and uniform after recrystallization. With the increase of nitrogen content, the strength of forging increases obviously and plasticity of forging decreases slightly. The yield strength and tensile strength of forging can be enhanced by 30 MPa and 50 MPa respectively when nitrogen content increases from 0.14 % to 0.20 %.
