“…36) Moreover, different types of quasi-constrained HPT was applied for the three-disk procedure on steel and vanadium under 6.0 GPa for 5 turns. 37,38) These numerous examples indicate the feasibility and the effectiveness of the unique HPT procedure for synthesizing hybrid alloy structures and ultimately MMNCs. It should be noted that the mechanical bonding by the noted bulk-state reactions by the application of HPT involves the processing of bulk metal disks and it should be differentiated from the mechanical alloying approach by using HPT for powder consolidation and mixing.…”

This report presents an overview of recent studies demonstrating a bulk-state reaction involving mechanical bonding through the application of high-pressure torsion (HPT) processing on two dissimilar engineering metals. This processing approach was developed by revising the sample setup and applying the simple procedure of alternately stacking two different metal disks using several different metal combinations. Thus, this report describes the development in microstructure after the bulk-state reactions and the mechanical properties of the HPT-induced AlMg, AlCu, AlFe and AlTi alloy systems. A microstructural evaluation confirmed the capability of the HPT procedure for the formation of heterostructures across the disk diameters in these processed alloy systems. Tribology tests and hardness values together with density measurements demonstrated an improved wear resistance and an exceptional specific strength in these alloy systems. The bulk-state reaction by HPT demonstrates a considerable potential for the bonding of dissimilar metals and the fabrication of unique metal systems.

“…The approach of a bulk-state reaction by HPT was studied mainly for the synthesis of hybrid metal systems by utilizing conventional HPT processing through the direct mechanical bonding with significant grain refinement of bulk dissimilar metal disks. In practice, this type of bulk-state reaction by HPT has been demonstrated for Al-Fe, [31] Al-Ti, [31] Cu-Al, [26] Mg-Zn, [48] Fe-V, [49,50] and V-10Ti-5Cr/Zr-2.5Nb [51] systems and a microstructural evaluation has confirmed the capability of the unique HPT processing for rigid bonding with severe mixture of the dissimilar metals and ultimately the formation of unique hybrid nanomaterials in these processed alloy systems. Moreover, this strategy can be successfully applied to a set of alternately stacked 19 Cu and 18 Ta thin foils to form a bulk solid under pressure for up to 150 turns.…”

The present study demonstrates an innovative approach of utilizing high‐pressure torsion (HPT) processing for the mechanical bonding of dissimilar metals during the microstructural refinement process. This processing approach has been developed recently for introducing unique alloy systems with improving physical and mechanical properties. Accordingly, the present study focuses specifically on the microstructural evolution and development in micro‐mechanical responses in the mechanically bonded Al‐Mg and Al‐Cu hybrid alloy systems when synthesized by HPT processing for very high number of turns up to 60 under 6.0 GPa at room temperature. The microstructural and hardness evaluations confirm the capability of the HPT procedure for the formation of heterostructures with extreme hardness at the disk peripheries and with low hardness at the disk centers in these processed alloy systems. Nanoindentation measurements demonstrate that both hybrid alloy systems exhibit excellent plasticity at the disk edges, where the hardness is the highest. There is a considerable potential for applying the solid‐state reaction through the HPT process for the bonding of dissimilar metals as a manufacturing technique and for the development of hybrid alloy systems.

“…up to 20 turns [38] under 6.0 GPa at RT where the disks were stacked alternately in the order of Al/Mg/Al without any adhesive treatments, as shown in Figure 4. [35] This procedure of HPT processing was further applied for several different metal combinations by stacking two disks of Al/Mg [39] and three disks of Al/Cu/Al, [40] Al/Fe/Al, [41] Al/Ti/Al, [41] Cu/Al/Cu, [42] Cu/ZnO/ Cu, [43] Zn/Mg/Zn, [44] Fe/V/Fe, [45,46] and V-10Ti-5Cr/Zr-2.5Nb/ V-10Ti-5Cr. [47] It should be noted that some of these listed combinations of dissimilar metals for mechanical bonding by HPT use different sample volumes by changing the disk thicknesses.…”

An overview of the mechanical bonding of dissimilar bulk engineering metals through high‐pressure torsion (HPT) processing at room temperature is described in this Review. A recently developed procedure of mechanical bonding involves the application of conventional HPT processing to alternately stacked two or more disks of dissimilar metals. A macroscale microstructural evolution involves the concept of making tribomaterials and, for some dissimilar metal combinations, microscale microstructural changes demonstrate the synthesis of metal matrix nanocomposites (MMNCs) through the nucleation of nanoscale intermetallic compounds within the nanostructured metal matrix. Further straining by HPT during mechanical bonding provides an opportunity to introduce limited amorphous phases and a bulk metastable state. The mechanically bonded nanostructured hybrid alloys exhibit an exceptionally high specific strength and an enhanced plasticity. These experimental findings suggest a potential for using mechanical bonding for simply and expeditiously fabricating a wide range of new alloy systems by HPT processing.
