Dynamics Simulations

High-resolution transmission electron microscopy investigations revealed different types of deformation structures in a nanostructured commercial Al–Mg alloy processed by high pressure torsion at room temperature. Microtwins and stacking faults were detected within both nanocrystalline grains and ultrafine grains. Full dislocations in the form of dipoles were observed within grains and near the grain boundaries. Two twinning mechanisms previously predicted by molecular-dynamics simulations were directly verified including the heterogeneous twins nucleated by the successive emission of Shockley partials from grain boundaries and homogeneous twins formed in the grain interiors by the dynamic overlapping of stacking faults. Hence, the formation of full dislocations, stacking faults and twins in the present aluminum alloy subjected to severe plastic deformation may be interpreted in terms of molecular-dynamics simulations based on generalized planar fault energy curves for pure metal systems.

High-pressure torsion was performed on commercial magnesium disks under uniaxial compression and simultaneously shear straining for different number of turns. Microstructural evolution during the severe plastic deformation process has been investigated by X-ray diffraction line profile analysis. Complementary hydrogen absorption experiments in a Sieverts’-type apparatus indicated that hydrogen storage and the microstructural parameters exhibit correlation.
