Commercially pure alpha-titanium was deformed by hot rolling at 268 o C for re- duction levels of 40%, 60% and 80%. The dislocations densities and types in terms of Bur- gers Vector Populations at different deformation rates were established using X-

The nanostructural features of the gas-phase displacement reaction 2Mg(g)+SiO2→2MgO(s)+{Si}, where SiO2 is in the form of diatom shells were studied via X-ray diffraction and Fourier methods. Diatomaceous powder heated to 700 °C in a sealed graphi

X-ray Peak Profile Analysis was employed to determine the evolution dislocation density and dislocations type in hot rolled commercially pure titanium specimens. It was found that 〈 a 〉 dislocation type is dominating the deformation mechanism at

Diffraction peak profiles broaden due to the smallness of crystallites and the presence of lattice defects. Strain broadening of powders of polycrystalline materials is often anisotropic in terms of thehklindices. This kind of strain anisotropy has b
