Plastic strain accumulation behaviour of AH32 steel in a cyclic stress-corrosion environment

Using AH32 steel as the material of interest, the present study fabricated partially corroded steel specimens based on the principle of Faraday's law. AH32 steel specimens with different corrosion losses were subjected to uniaxial cyclic loading tests at room temperature; these tests considered the effects of the number of initial loading cycles, the stress ratio (R), the R history, alternating tensile-compressive and high stress to reveal the characteristics of the plastic strain accumulation behaviour of AH32 steel under the combined effect of the cyclic stress and corrosion factors.
