Thesis Overview

The project titled "Investigation of the Corrosion Behavior of Advanced High-Strength Steels in Various Environments" seeks to explore the response of advanced high-strength steels to different environmental conditions with a specific focus on corrosion behavior. High-strength steels are widely used in various industries due to their superior mechanical properties, which make them ideal for applications requiring high strength and durability. However, the susceptibility of these materials to corrosion can significantly impact their performance and service life, leading to potential safety and economic implications. The research will begin with a comprehensive literature review to establish the current understanding of corrosion mechanisms in high-strength steels and the factors influencing their corrosion resistance. This review will cover key concepts related to corrosion, types of corrosion processes, factors affecting corrosion resistance, and existing studies on the corrosion behavior of high-strength steels in different environments. By synthesizing existing knowledge, the research aims to identify gaps in the current understanding and lay the foundation for the experimental investigation. The experimental phase of the study will involve conducting corrosion tests on advanced high-strength steels in various simulated environmental conditions, including aqueous solutions, atmospheric exposure, and aggressive chemical environments. Different corrosion testing methods, such as electrochemical impedance spectroscopy, potentiodynamic polarization, and weight loss measurements, will be employed to evaluate the corrosion resistance of the materials under different conditions. The collected data will be analyzed to assess the corrosion behavior of the steels, identify potential corrosion mechanisms, and quantify the extent of corrosion damage. Furthermore, the study will investigate the influence of alloy composition, microstructure, surface treatments, and environmental factors on the corrosion resistance of advanced high-strength steels. By systematically varying these parameters and analyzing their effects on corrosion performance, the research aims to provide insights into the design and optimization of high-strength steel alloys for enhanced corrosion resistance in practical applications. The findings of this research are expected to contribute to the development of strategies for mitigating corrosion in high-strength steel structures exposed to challenging environmental conditions. The knowledge generated through this study will have implications for industries such as automotive, aerospace, marine, and construction, where high-strength steels are used in critical components and infrastructure. Ultimately, the research outcomes will advance the understanding of corrosion behavior in advanced high-strength steels and support the development of more durable and reliable materials for demanding applications.
