Abstract

The corrosion failure mechanism of Q235 steel under different stresses in simulated marine environment was investigated. The corrosion products of Q235 steel under different stresses are characterized. Additionally, electrochemical experiments and finite element simulations were conducted to examine the corrosion behavior of Q235 steel under various stress conditions. Stress promotes the corrosion failure of Q235 steel and accelerates the generation and transformation of corrosion products. Different stress levels lead to distinct stress corrosion mechanisms, with lower stress levels increasing sensitivity to corrosion. Elevated levels of stress result in stress concentration in dislocation defects, leading to more severe localized corrosion. A model for the evolution of stress corrosion failure has been established, revealing that the corrosion behavior at different stress levels is not strictly independent and can transition from low to high stress conditions under certain circumstances. Furthermore, it was observed that even at low stresses, there can be occurrences of stress concentrations leading to localized corrosion.

期刊介绍： Pressure vessel engineering technology is of importance in many branches of industry. This journal publishes the latest research results and related information on all its associated aspects, with particular emphasis on the structural integrity assessment, maintenance and life extension of pressurised process engineering plants. The anticipated coverage of the International Journal of Pressure Vessels and Piping ranges from simple mass-produced pressure vessels to large custom-built vessels and tanks. Pressure vessels technology is a developing field, and contributions on the following topics will therefore be welcome: • Pressure vessel engineering • Structural integrity assessment • Design methods • Codes and standards • Fabrication and welding • Materials properties requirements • Inspection and quality management • Maintenance and life extension • Ageing and environmental effects • Life management Of particular importance are papers covering aspects of significant practical application which could lead to major improvements in economy, reliability and useful life. While most accepted papers represent the results of original applied research, critical reviews of topical interest by world-leading experts will also appear from time to time. International Journal of Pressure Vessels and Piping is indispensable reading for engineering professionals involved in the energy, petrochemicals, process plant, transport, aerospace and related industries; for manufacturers of pressure vessels and ancillary equipment; and for academics pursuing research in these areas.
