Abstract
Typical experimental situations of texture measurements are demonstrated involving failure to take into account some physical factors responsible for an inadequate texture description or imaginary texture changes. Among these factors there are inevitable texture inhomogeneities, inhomogeneous distribution of defects in deformed metal materials and resulting inhomogeneous lattice perfection by their heat treatment. It is shown that a formal approach to texture analysis does not allow to reveal a number of important regularities of structure formation.
