    Abstract
  • The influences of surface morphology and corrosion time of Q345 steel after strong corrosion on its mechanical property degradation were systematically studied. A rapid corrosion method based on the industrial hydrochloric acid with a concentration of 36% at room temperature was adopted, and nine groups of steel specimens with the corrosion time of 0, 1, 2, 4, 8, 12, 24, 48, and 72 h respectively were designed. A 3D non-contact laser scanner and an electron microscope were adopted to scan the corroded steel, and the width and height of the largest corrosion pit and the thicknesses of corroded specimens were measured. The influence coefficient of the largest corrosion pit was calculated. A tensile test was carried out, and the mechanical property degradation mechanism of Q345 steel after strong corrosion was explained according to the scanning morphology and microstructure morphology. The corrosion kinetics curve and constitutive relation model of Q345 steel after strong corrosion by the industrial hydrochloric acid with a concentration of 36% were established at room temperature, and the mechanical property degradation law of Q345 steel after strong corrosion was revealed. Research results show that as the corrosion time increases, the corrosion kinetics curve of Q345 steel demonstrates the change law of corrosion rate. When the corrosion time is less than 1 h, the influence coefficient of the largest corrosion pit increases obviously, and the nominal yield strength, nominal tensile strength, nominal elastic modulus and elongation of the steel degrade significantly, reaching 3.00%, 0.69%, 1.99%, and 4.88% of the uncorroded steel respectively. When the corrosion time exceeds 12 h, the influence coefficient of the largest corrosion pit increases slowly, and the nominal yield strength, nominal tensile strength, nominal elastic modulus and elongation of steel degrade slowly, reaching 7.58%, 4.02%, 10.27%, and 26.64% of the uncorroded steel respectively. The change of the yield-strength ratio is slight as the influence coefficient of the largest corrosion pit and the corrosion time increase. In the stress-strain constitutive relation curves of the corroded specimens, as the corrosion time increases, the yield platform of steel gradually shortens or even disappears, and the steel changes from ductile failure to brittle failure.
