Gas-pressure forming of superplastic ceramic sheet

, 1993
Superplasticity in ceramics has now advanced to the stage that technologically viable superplastic deformation processing can be performed. In this paper, examples of biaxial gas-pressure forming of several ceramics are given.

Hybrid superplastic forming of magnesium alloys

, 2015
Superplastic forming has been a useful process applied in the manufacture of complex components in the automotive and aerospace industries with high degree of precision. However, this technology requires expensive materials with fine grain sizes and high

Superplastic forming using NIKE3D [PDF]

, 1996
The superplastic forming process requires careful control of strain rates in order to avoid strain localizations. A load scheduler was developed and implemented into the nonlinear finite element code NIKE3D to provide strain rate control during forming ...

One-step fabrication of crystalline metal nanostructures by direct nanoimprinting below melting temperatures

Nature Communications, 2017
Rapid fabrication of well-controlled metallic nanostructures remains a challenge. Here, the authors directly nanoimprint several different crystalline metals by superplastic forming well below their melting temperatures, obtaining uniform nanostructures ...

Adaptive Superplastic Forming Using NIKE2D with ISLAND

, 1992
Superplastic forming has emerged as an important manufacturing process for producing near-net-shape parts. The design of a superplastic forming process is more difficult than conventional manufacturing operations, and is less amenable to trial and error ...

Finite element analysis of high strain rate superplastic forming (SPF) of Al–Ti alloys

, 2002
Presents the numerical results obtained from the finite element analyses of the superplastic forming (SPF) of Al–Ti alloys. The models are used to optimise the process and predict forming times in terms of deformed shapes, stress–strain distributions and

Superplastic Forming of Micro Components

, 2003
A method for forming a miniaturized shaped component. Bulk superplastic material is contacted with a flat rotating surface of a rotating tool to frictionally heat the bulk superplastic material with the bulk superplastic material positioned between the ...
