The equation of p-V state for sheet crystallites of the #alpha#-Ti alloy PT-3Vkt after the cross hot rolling followed by the cold rolling is considered. A pressure value is obtained as the hydrostatic component of the residual macrostresses tensor calculated from the X-ray measurements of residual strain according to Hooke's law. The compliance tensor components of crystallites are found for each deformation degree of sheets within the Hill's approximation on a base of experimental Young's modulus anisotropy and the integral characteristics of texture. A value of crystallite volume is estimated on a base of X-ray investigations. The empirical potential of Ti alloy is used as a potential of interatomic interaction. It is found the p-V-equation that satisfactorily describes the experimental data on the studied PT-3Vkt alloy sheets.
