Ultrafine-grained and heterostructured materials are currently of high interest due to their superior mechanical functional properties. Severe plastic deformation (SPD) is one the most effective methods produce such with unique microstructure-property relationships. In this review paper, after summarizing recent progress in developing various SPD for processing bulk, surface powder materials, main structural microstructural features SPD-processed explained including lattice defects, grain...
Both numerical simulation and hardness measurements were used to determine the mechanical microstructural behavior of AZ31 bulk samples when submitted Equal Channel Angular Pressing (ECAP) technique. Billets this representative Mg-rich alloys different numbers passes for various ECAP modes (anisotropic A, isotropic BC). The strain distribution, grain size refinement, micro-hardness as indicators quantify effectiveness processing routes. Structural characterizations at scales achieved using...
The kinetics of magnesium hydride formation depends on many factors such as thermodynamic conditions, the presence/absence additives and mechanical treatments applied to starting material. As a result, impact reaction material is complex. Additionally, during repeated hydrogenation/dehydrogenation cycles, microstructure becomes significantly different from original one. In case, it not so simple order relative importance experimental contributions. fact limited research efforts have been...
The study of metal forging over long period time has made it possible to establish the major basic principles up most recent, those Severe Plastic Deformation (SPD). Thus fundamental characteristics resulting from stresses and deformations applied have led definition modelling microstructural variations in grain size shape, density dislocations, slip bands twins, all factors be considered during transformation micro/nanostructure by SPD. For this purpose, SPD techniques such as ECAP, HPT,...

The paper presents the results of using a pressing process well known in metallurgy as forging. However, here Fast Forging is used new way to synthesize materials having e.g. high hydrogen sorption capacity. Firstly, method allows delivering final consolidated product from initial Mg and Ni powdered elements during pressing. Secondly, it enables phase transformation, i.e. synthesizing Mg2Ni binary Mg-Ni mixture powders, which unique result. It established that key point formation sample...
There are many different systems of an autonomous energy storage including accumulators and devices for renewable energy. Systems based on reversible metal hydrogenation have recently been introduced. The selection metals is considerations temperature pressure conditions the hydrogenation/dehydrogenation cycle, as well desired hydrogen capacity. Magnesium one main challenging with respect to these since having a capacity up 7.6 w.%. For Mg forming MgH2, it was soon established that size...
