Abstract

The objective of this work is to analyze the high-cycle fatigue performance of the corroded base material without joints. Constant-amplitude axial tensile fatigue tests were conducted on 55 specimens obtained from the various environments. The infrared thermography was used to track the surface temperature of the specimens. When the corrosion degree is close, the accelerated corrosion test can simulate the atmospheric corrosion to predict the fatigue performance. The mechanism of discreteness of fatigue damage was analyzed from the perspective of energy dissipation. The S-N curves suitable for the Q235 steel in the acid rain corrosion environment are developed.
