Ultralow-temperature superplasticity and its novel mechanism in ultrafine-grained Al alloys
Materials Research Letters, 2021 The important benefits of ultrafine-grained (UFG) alloys for various applications stem from their enhanced superplastic properties. However, decreasing the temperature of superplasticity and providing superplastic forming at lower temperatures and higher

A method for estimating superplastic material parameters via free–inflation tests
Journal of Materials Research and Technology, 2021 In this work, a new methodology for evaluating the constitutive parameters of superplastic materials is presented. The proposed methodology provides the characterization of the material by means of a variable called apparent viscosity.

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.Abstract The Mont Blanc granite, as other deformed granites, has splitting properties attributed to two perpendicular planes: one formed by aligned fractures and the other by aligned micas in foliation planes. It is shown that this microstructure results from ductile deformation with stress‐driven dissolution of quartz and feldspar that passively ...

Material model calibration for superplastic forming [PDF]
, 2019 Superplastic forming is a slow forming process. The forming time can be minimized by optimizing the pressure profile applied to the forming sheet. The optimization of the superplastic forming pressure is usually done such that a target strain rate at a ...
