| 摘 要： | 测定了控氮00Cr13Ni4Mo(S13-4N)与低氮00Cr13Ni6Mo(S13-6)的性能,对比分析了氮元素对00Cr13Ni4Mo的强度、韧性、耐蚀性的影响。力学性能测试结果表明,回火温度≤550℃时,控氮的S13-4N比低氮的S13-6的强度更高,韧性更低;回火温度≥550℃时,规律逐渐变得相反;S13-4N在450℃左右出现回火脆性现象。电化学测试结果表明,S13-6的耐点蚀性能优于S13-4N。XRD和EBSD结果表明,两种钢在550℃以上温度回火时出现逆变奥氏体,600℃附近含量达到最大值,此时的韧性最佳,S13-6中的逆变奥氏体总量多于S13-4N,但形态不同。分析认为:氮比镍稳定奥氏体的能力强,而镍形成逆变奥氏体的能力则更强,逆变奥氏体的含量和稳定性对韧性的影响很大;S13-4N的450℃回火脆性主要是由于碳化物和氮化物的析出引起的。

| Abstract: | The mechanical and corrosive properties of 00Cr13Ni4Mo(S13-4N) were tested and compared with those of 00Cr13Ni6Mo(S13-6).The effects of nitrogen on the properties of the 00Cr13Ni4Mo were analyzed.The results of the mechanical property tests show the strength and ductility of S13-4N are higher and poorer than those of S13-6 respectively,when tempered at a temperature below 550℃ and vice versa when the tempering temperature is higher than 550℃.S13-4N s temper embrittlement phenomenon appears at about 450℃.The... |
