Superplastic Deformation and Superplastic Forming.
Journal of the Japan Society of Powder and Powder Metallurgy, 1991 The paper were reviewed recent researches of parameters which control the flow and ductility of micrograin superplastic materials. Particular attention was emphasized to the strain rate sensitivity of the flow stress, m and high rate superplasticity. It has been pointed out that the origin of these characteristics is the grain boundary sliding process,

steel research international, EarlyView.Strain‐induced NbC precipitation governs hot‐deformation resistance in CrNiMnMoB ultrahigh‐strength steel by suppressing dynamic recrystallization, increasing activation energy, and refining martensitic substructures. The precipitation response is controlled by temperature, supersaturation, and strain rate, with slow deformation promoting extensive NbC

Ceramics International, 1989 Superplastic elongation of fine-grained ceramics can be observed when some mechanical and microstructural requirements are satisfied at appropriate test conditions, temperature and strain rate. The phenomenon can be utilized in superplastic forming, solid-state bonding, sinter-forging, hot press, and hot-isostatic pressing.
