Investigation of Superplastic Forming Process through FEA to Minimize the Forming Defects: A Literature Review

  Gaivin D. Kushvaha,  Jaydeep R. Shah

Superplastic forming is the ability of certain alloys, to undergo very large elongations, prior to fracture without neck formation. Material with more than 200% elongation during hot tensile testing are said to have superplastic forming capability. The low flow stresses and high sensitivity of flow stress to strain rate are the main aspects of superplastic deformation. Superplastic forming mainly used in aerospace and automobile sector where complex shapes required for fine and thin material without any damage. Quality of superplastic formed material mainly depend on Forming pressure, Dome height Sensitivity index, Effective strain at the dome apex and Annealing time. Purpose of this study is to minimizing the forming defects with balancing the factors having more influence on it.
