Severe plastic deformation (SPD) is effective in producing bulk ultrafine-grained and nanostructured materials with large densities of lattice defects. This field, also known as NanoSPD, experienced a significant progress within the past two decades. Beside classic SPD methods such high-pressure torsion, equal-channel angular pressing, accumulative roll-bonding, twist extrusion, multi-directional forging, various continuous techniques were introduced to produce upscaled samples. Moreover,...
Wear resistant highly amorphous Fe60Cr8Nb8B24 (at.%) coatings of about 280 μm thickness were prepared through high velocity oxygen fuel (HVOF) thermal spray process onto API 5L X80 steel substrate. Feedstock powders produced by gas atomization with low purity precursors modifying AISI 430 stainless additions niobium (Fe-Nb) and boron (Fe-B). It was found that the mostly some embedded FeNbB Fe2B borides. The formation a large fraction phase attributed to cooling rates molten droplets combined...
Abstract MgH 2 is a promising material for solid‐state hydrogen storage due to its high gravimetric and volumetric capacity relatively low cost. Severe plastic deformation (SPD) processing techniques are being explored as an alternative high‐energy ball‐milling (HEBM) in order obtain more air resistant materials reduce times. In this work, Mg, , –Fe mixtures were severely mechanically processed by different such high‐pressure torsion (HPT), extensive cold forging, rolling. A very significant...
In this paper, we report an investigation of adding a non-hydride forming element in the multicomponent Ti-V-Nb-M system. By Calculation Phase Diagrams approach (CALPHAD), thermodynamic phase stability TiVNbT (T = Cr, Mn, Fe, Co, and Ni) was investigated, Cr selected as fourth alloying due its high tendency to stabilize body-centered cubic solid solutions (BCC). The (TiVNb)100−xCrx alloys (with x 15, 25, 35 at.% Cr) were synthesized by arc-melting. structural characterization reveals that...
Abstract Quasicrystalline alloys and their composites have been extensively studied due to complex atomic structures, mechanical properties, unique tribological thermal behaviors. However, technological applications of these materials not yet come age still require additional developments. In this review, we discuss the recent advances that made in last years toward optimizing fabrication processes properties Al‐matrix reinforced with quasicrystals. We detail high‐strength rapid‐solidified...
