Superplasticity in an organic crystal [PDF]
Nature Communications, 2018 Superplasticity enables processing on hard-to-work solids but superelastic deformation, especially in a single-crystal-to-single-crystal manner, was not demonstrated for organic crystals so far.

Superplasticity and superplastic forming of ceramics [PDF]
Materials Science Forum, 1994 Recent advances in the basic understanding of superplasticity and superplastic forming of ceramics are reviewed. Deformation mechanisms as well as microstructural requirements for superplastic ceramics are discussed. Microstructural effects, such as grain size, dynamic grain growth, and the presence of grain-boundary liquid phases, on the superplastic ...

Superplastic deformation behavior of Mg alloys: A-review
Journal of Magnesium and Alloys, 2022 The magnesium alloys are the next-generation lightweight metal materials; however, the production of the complex shape components of thermo-mechanical processed magnesium alloys is very limited in comparison to their die-casted counterparts.

The Mechanics of Superplastic Forming - How to Incorporate and Model Superplastic and Superplastic-Like Conditions [PDF]
Materials Science Forum, 2016 Much work has been carried out in understanding the mechanics of superplasticity (SP). Some of the present challenges in SP forming revolve around the use of lower forming temperatures and faster strain rates, which may involve pushing the process boundaries to incorporate “superplastic-like” forming – perhaps also in materials with non-optimized ...

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
