Abstract

Pure magnesium is deformed up to fracture at various temperatures. The deformed samples are investigated by high resolution X-ray diffraction peak profile analysis. The diffraction peaks are fitted by theoretical profile functions where the strain profile is scaled for strain anisotropy by the dislocation contrast factors. The contrast factor parameters are evaluated in terms of the fundamental Burgers vector types in hexagonal crystals. The evolution of the dislocation density and the Burgers vector types with the temperature of deformation is discussed on the basis of dislocation reactions and dynamic recovery in magnesium.
