As the limitations of sheet metal fabrication are most often determined by the tensile ductility, superplasticity in sheet metals offers advantages for the forming of complex shapes easily as a regular production process.The focus of the present work is to arrive at the optimum process parameters in the superplastic forming in re-entrant shape of 7075 aluminium alloy, so as to achieve minimum thinning, lesser forming time and reduction in micro cavities.

Samples with x = 0.003 and 0.01 reveal a monotonous increase of low-temperature dielectric constant, corresponding to an enhancement of the tunability and a reduction of the driving electric field at 10-30 K for x = 0.01.
The lattice parameter was calculated by a least square approach fitting the XRD data using WinPLOTR software.
In particular, the maximum relative tunability was found to increase from 79.2% for undoped ST to 82.3% for Sr0.99Ca0.01TiO3 at 10 K under bias field Emax = 20 kV/cm, corresponding to a reduction of the driving electric field.
