Superplastic forming definition

Superplastic forming. (1 2) means a deformation process using heat for metals that are normally characterised by low values of elongation (less than 20%) at the breaking point as determined at room temperature by conventional tensile strength testing, in order to achieve elongations during processing which are at least 2 times those values.

  • Thermal expansion is other parameter to be considered in Superplastic forming dies.

  • This work presents a method to assess ceramic die wear by means of a novel test rig developed at the Advanced Forming Research Centre where the Superplastic forming die-part interaction can be replicated at laboratory scale.

  • The use of metallic tooling is associated with two major costs: production time scale costs (long lead times) and non-recurring tooling costs (design changes or corrections) [2], [7].Ceramic materials have been identified as a viable option for Superplastic forming dies due to their resistance to high temperatures, oxidation/reaction passivity, andeasy manufacturing characteristics.

  • The use of ceramics for Superplastic forming has been studied since the 1990s.

  • The total test time for each ceramic material simulated a typical lifespan of a ceramic Superplastic forming die.

  • Es wurden kontrollierbare Test unter Normalbelastung und unter üblichen Superplastische Formgebung-Bedingungen für drei verschiedene verstärktekeramische Materialien durchgeführt um deren Verschleißmechanismen zuverstehen und letztlich Methoden zur Verbesserung der Verschleißfestigkeit zu identifizieren.Keywords: Superplastic forming; ceramic, wear; tribology, friction, ceramic die.

  • In the work presented in this paper, three commercial reinforced ceramic materials were mechanically tested with the aim of evaluating their wear behaviour when subjected to Superplastic forming representative conditions and assessing their suitability for Superplastic forming dies.

  • The overall objective of this work was to expand the research in low cost die materials for Superplastic Forming processes.The reduction in cost of the Superplastic forming process may promote its wider use in the industry and reduce the production cost for the current users.

  • Despite their brittle nature, ceramic diesare a developing technology for Superplastic forming as they offer lower production costs and shorter lead times than conventional metallic dies, thus reducing process costs.

  • The trials were carried out at pressures of 2 MPa (3 kN applied load on the sample area) and 3 MPa (5 kN applied load on the sample area) and common Superplastic forming temperatures.
