Specific heat of a superplastically elongated 3Y-TZP (3 mol.% yttria stabilized tetragonal zirconia polycrystalline) was investigated. The experiments were conducted by a differential scanning calorimetry (DSC) method at a wide temperature range from 473 K to 1273 K. The experimental results were evaluated and discussed based on the results of microstructure information and phase composition investigations. It is concluded that superplastic deformation probably have no influence on the specific heat of 3Y-TZP ceramic.
