The intragranular strains were shown to be the main form of strains. It was established that the value of strain within one grain (up to 70 %) is much in excess of the total strain value (13 %). Strains are compensated for due to different orientations of slip planes in different grains. Plastic strains in boundary zones were calculated by the finite element method. Allowance for heterogeneity of grains and boundary zones in modelling indicated to the presence of additional strains amounting to 16-30 %.
