| Abstract Scope |
Ferrium® M54® is a medium-carbon ultra-high strength steel with the potential for achieving outstanding strength, toughness, and stress corrosion cracking resistance. A sheet rolling process involving repeated low-percentage rolling reductions, referred to as Skin Pass Rolling (SPR), was investigated to reveal the relationships between processing, microstructure, and mechanical properties. Rolling was conducted dry at 23 °C with final reductions of 10% - 60% at between 0.5% - 3% per-pass. Subsurface hardening was assessed via Rockwell Hardness and confirmed locally by Vickers Microhardness. After processing, mechanical performance and tensile testing was evaluated across the range of final reductions, with digital image correlation strain mapping. Microstructural investigations of the microstructure (phases present and block and lathe structures) point to the mechanisms for the low-temperature plasticity and resultant mechanical properties. The results forecast the ability to use Skin Pass Rolling to improve formability and enhance the performance of novel ultra-high strength steel products. |
