中文摘要：采用透射电镜、X-射线衍射等技术研究了Ni含量对0Cr17Ni4Cu4Nb不锈钢中逆转变奥氏体的影响。结果表明，随着Ni含量的提高，时效过程中发生逆转变奥氏体的温度降低，且在相同的时效温度下得到的逆转变奥氏体含量增多。在淬火缓冷的情况下，随Ni含量的降低，时效后钢中的残余奥氏体含量增加。
英文摘要：The effect of Ni content on reverted austenite in 0Cr17Ni4Cu4Nb stainless steel was studied by TEM, X-ray diffraction, etc. The results show that, with the increase of Ni content, the temperature of reverted austenite falls during aging, and the content of reverted austenite aged at the same temperature increases. Under the condition of quenching with slow cooling, the content of residual austenite in the steel after aging increases with the decrease of Ni content.
