Title:
Representing the Superplasticity of Inconel 718
Authors:
Zhang, B.; Mynors, Diane J.; Mugarra, A.; Ostolaza, K.
Abstract:
Modelling the superplastic process using finite element analysis can enable optimum process parameters to be determined and lead to a better understanding of the process. Constitutive equations, which accurately represent a material’s behaviour, are very important in the development of representative process models. The development of a set of constitutive equations for superplastic grade Inconel 718 alloy based around a hyperbolic sine relation is described in this paper. The hyperbolic sine relation with strain dependant parameters is shown to represent the relationship between stress, strain and strain rate over a wide strain range. The valid strain range is sufficient to cover both strain hardening and flow softening behaviour.

Description:
This paper, with another by the authors in Materials Science Forum, 2004 (Vol 447/448, pp 171-176), describes the first constitutive equation for superplastic forming grade INCONEL 718. The equation is essential for the simulation of the superplastic forming of INCONEL 718 aerospace components and is now being utilised, with 98% accuracy, by: Industria de Turbo Propulsores, S.A.
