The pure metal was deformed up to fracture at various temperatures. The deformed samples were then investigated by using high-resolution X-ray diffraction peak profile analysis. The diffraction peaks were fitted using theoretical profile functions in which the strain profile was scaled, for strain anisotropy, by the dislocation contrast factors. The contrast factor parameters were evaluated in terms of the fundamental Burgers vector types in hexagonal crystals. The evolution of the dislocation density and the Burgers vector types, as a function of deformation temperature, were considered on the basis of dislocation reactions and dynamic recovery.
