Work hardening of ultra-high-strength steels and influence of temperature on their strain hardening behaviour : experimental work on S960MC and S1100

Abstract

This study examines the behavior of ultra-high-strength steels, S960 and S1100, under high temperatures through tensile testing. The research aims to assess their mechanical capabilities and deformation traits. Tensile tests are conducted, and key mechanical characteristics are analyzed, including yield strength, ultimate tensile strength, and elongation at high temperatures. The findings reveal that both steels experience changes in mechanical behavior at elevated temperatures, with decreased strength and increased ductility. S1100 steel demonstrates improved high-temperature mechanical qualities compared to S960 steel. The study provides valuable insights for selecting the appropriate steel in high-temperature environments, ensuring the reliability of engineering. These findings hold utmost significance in the context of selecting the most appropriate steel for applications in high-temperature environments, thereby ensuring the reliability and performance of engineering systems. By shedding light on the specific mechanical responses of S960 and S1100 steels to elevated temperatures, this study offers valuable insights that can inform decision-making processes across diverse industries, facilitating the optimal selection of materials for applications subject to high-temperature conditions. Consequently, this research contributes to advancing the understanding of steel behavior under thermal stress and supports the development of more robust and efficient engineering solutions.
