| Abstract Scope |
We present a novel processing approach – metal peeling – for producing high-performance sheet steels for structural applications. Unlike rolling, metal peeling utilizes controlled material removal, or cutting, to produce thin metal strips in a single deformation step. Besides its ability to reduce energy and carbon footprint, the process also offers opportunities to achieve unconventional microstructures (e.g., nanocrystalline/non-equilibrium) through the exploitation of intense deformation conditions underlying strip peeling. Plastic strains up to 5 can be imposed in a single step under strain rates of 10^3 to 10^5 /s. This talk will describe findings from studies with two classes of steel (austenitic stainless steel and ferritic/martensitic steel) of relevance to nuclear cladding structural applications. Observations pertaining to microstructure and phase evolution during deformation processing and its impact on the strip properties will be presented. Opportunities for achieving improved high-temperature properties and >1 GPa strength using commodity steel grades will be discussed. |
