  • Based on the analysis and processing of the fatigue test results of the standard specimens of the TA15 Titanium alloy thin plate and the fatigue test results of the plate at two stress levels, the S-N curve of TA15 plate was established. The fatigue tests at two stress levels were carried out for TA15 electron beam welding plate. The equivalent theoretical stress concentration coefficient of the welded specimens, the mean equivalent theoretical stress concentration coefficient and the reliable equivalent theoretical stress concentration coefficient were determined. Then, the S-N and p-S-N curves for the welded specimens were established. The equivalent Kt method was proved reasonable. Finally, a comparison was made between the fatigue properties of these two kinds of specimens.
