介绍了大量经不同处理的Ｃｒ１８Ｎｉ９型不锈钢试样的ＥＰＲ数据测试结果，并基于这些结果对以Ｓｔｒａｕｓｓ测试为基础建立的ＲｏｃｈａＴＴＳ－Ｓ图进行了修正，修正后的关系图符合实验结果，并得到以下结论：①修正后ＴＴＳ－Ｓ图的晶间腐蚀区域大于Ｒｏｃｈａ图中的晶间腐蚀区域；修正后的ＴＴＳ－Ｓ图中的Ｔｍ线高于Ｒｏｃｈａ图中的Ｔｍ线。②当游离碳小于０．０６％时，修正后ＴＴＳ－Ｓ图上的各Ｔｍ点比Ｒｏｃｈａ图上的各Ｔｍ点发生的时间短，相应各Ｃ形曲线前移；当游离碳大于０．０６％时，修正后ＴＴＳ－Ｓ图上的各Ｔｍ点比Ｒｏｃｈａ图上的各Ｔｍ点发生的时间长。③修正后ＴＴＳ－Ｓ图上的稳定性数值Ｓ比Ｒｏｃｈａ图上的Ｓ值低４×１０－５。
The EPR data of a large number of different treated Cr18Ni9 stainless steel samples are introduced and the RochaTTS-S map based on the Strauss test is revised based on these results. The corrected relationship is in agreement with the experimental results and the following results are obtained Conclusion: (1) The corrected intergranular corrosion area of TTS-S diagram is larger than the intergranular corrosion area of Rocha chart. The Tm line in the modified TTS-S diagram is higher than the Tm line in Rocha diagram. ② When the free carbon is less than 0.06%, the corrected TTS-S maps show that each Tm point is shorter than the Tm points on the Rocha chart and the corresponding C-shaped curves move forward. When the free carbon is greater than 0.06 %, The Tm points on the TTS-S map after correction are longer than the Tm points on the Rocha chart. ③ After correction, the stability value S on the TTS-S graph is 4 × 10-5 lower than the S value on the Rocha graph.
