| Abstract Scope |
The role of grain refinement on the mechanical properties via a severe plastic deformation (SPD) technique known as equal channel angular pressing (ECAP) in three high strength steels is investigated. The steels studied in the present work are HY-100, a low carbon, low alloy martensitic steel known for its high yield and ultimate tensile strength widely used in various naval applications due to the combination of its high strength, weldability, formability, and corrosion resistance; AF9628, which is a newly developed high strength martensitic steel known for exceptional strength and toughness; and FeMnAl, an austenitic steel alloy known for its high strength to weight ratio due to the addition of Al, which reduces weight and increases precipitation hardenability. The selected number of ECAP passes, routes, and processing temperatures produced a variety of enhancements in mechanical properties for these materials where significant strengthening after ECAP via microstructural refinement is achieved. |
