Superplasticity in Ultrafine-Grained Materials. [PDF]
Reviews on Advanced Materials Science, 2018 Superplasticity refers to the ability of a polycrystalline solid to exhibit a high elongation, of at least 400% or more, when testing in tension. The basic characteristics of superplastic flow are now understood and a theoretical model is available to ...

Journal of Materials Research and Technology, 2023 Borides are usually hard and brittle materials; however, we report the synthesis of superplastic nanostructured NdB6 ceramic powders, counter to the conventional wisdom that borides are always brittle. We investigate that through strain engineering, NdB6

Role of Grain Size and Shape in Superplasticity of Metals
Frontiers in Materials, 2021 Superplasticity is characterized by an elongation to failure of >300% and a measured strain rate sensitivity (SRS), close to 0.5. The superplastic flow is controlled by diffusion processes; it requires the testing temperature of 0.5Tm or greater where
