| Abstract Scope |
Ferrium® M54® is a computationally designed medium-carbon ultra-high-strength steel (UHSS) designed for outstanding strength, toughness, and stress corrosion cracking resistance. Observations from the study of ambient temperature rolled samples forecast the development of highly refined microstructural features with plasticity retention. Yet, limited work has been done to explore the cold workability of these as-hardened materials. A process involving low-percentage rolling reductions at ambient temperatures, called Skin Pass Rolling (SPR), was investigated to reveal the relationships between processing, feature morphology, and mechanical properties at cumulative rolling reductions of 10-60%. Tensile strength was increased to a maximum of 2789 MPa as compared to the direct-quenched state (1916 MPa) and the ausformed + tempered state (2222 MPa). This study has allowed us to enhance the mechanical properties of as-hardened UHSS and demonstrate a path forward for future high-specific-strength steels. |
