Relations between texture, superplastic deformation and mechanical properties of thin TA6V slabs

Superplastic tensile tests have been carried out up to elongations of 20 and 100% at 925°C on a thin TA6V slab. To study the influence of texture, test pieces axes have been oriented with four angles from the rolling direction. No pronounced effect of texture on superplastic behaviour is clearly enhanced by the usual stress/strain rate law. The type of microstructural changes and the variations of the texture intensity may be correlated with the strain range. As for the starting material, tensile properties of the stretched material at room temperature are strongly dependent on texture.
