The microstructures and textures of TA15 titanium alloy after hot deformation under different process parameters were investigated by X-ray diffractometry (XRD) and electron back scattering diffractometry (EBSD). The results indicate that microstructures of TA15 alloy appear obvious acicular martensite α' phase after hot deformation and quenching. The plastic deformation is going to occur in the slip systems of (101) and (002) slip planes by first reaching the critical resolved shear stress. The strong recrystallization textures are achieved at low deformation temperature and low strain rate, which will be weakened with increasing the strain rate and temperature.
