The microstructure evolution of material is impact directly the mechanic performance of the component in superplastic forming.
The growth grain will fall the distortion capability of materials and brings cracks and ruptures easily.

The calculated elastic properties are coherent with the elastic properties of the material.
Among these materials, Ti3Al presents an anomalous (positive) temperature dependence of yield and flow strength with a high ordering energy, and this is the basis for the mechanical properties of modern superalloys[1].
Elastic properties The elastic constant is correlated to the strength of materials.
The Young modulus, shear modulus, Zener modulus (anisotropy), and Poisson modulus are frequently measured for polycrystalline materials when investigating hardness in order to demonstrate the relationship between microscopic and macroscopic quantities.
