Notes:
Both tensile and strain controlled low cycle fatigue (LCF) tests were conducted for 316Land 316LN at 550oC and 600oC to investigate the nitrogen effect on the deformation behavior oftype 316L stainless. The waveform of LCF was a symmetrical triangle with a constant strain rate of4×10-3/s was employed for most tests. It shows that the addition of nitrogen in the alloy results in anincrease in tensile strength but a decrease in ductility. Both the alloys exhibited cell structure aftersevere tensile deformation. However, after low cycle fatigue, only planar slip band is observed in316LN, whereas cell structure is still the main feather of microstructure in 316L. This is due to thestrong interstitial-substitutional Mo-N pairs and various stress strain conditions
