Abstract
Superplasticity is a unique material property by which a polycrystalline material exhibits very high tensile elongation in all directions prior to failure. The paper presents the geometrical modelling of the depth of form from the displaced air volume from the gas blow forming die. The formability of the material could be understood and the time required for forming could be estimated for different pressures of the gas. The variation in sheet thickness with constant strain rate during forming is calculated for different arc thickness. The plotted graphs of the geometrical model are compared with the computational results performed in MSC MARC MENTAT. The variation in sheet thickness of the Magnesium alloy sheets coated with aluminum alloy into a conical die is investigated experimentally. The thickness variation of the formed shows a close agreement with the theoretical and computational models.
