High entropy alloys (HEAs) are well known for their excellent mechanical properties compared to conventional metallic alloys. The application of High-Pressure Torsion (HPT) processing reduces grain size of materials away below 1 µm. This significant grain refinement leads to an improvement in mechanical properties, such as strength and ductility. In...
High-pressure torsion (HPT) is an effective severe plastic deformation (SPD)
technique to produce bulk nanostructured materials (BNMs). These BNMs often show a combination of exceptional mechanical and physical properties. Processing of single metals and alloys by HPT has been understood that the homogenous microstructures can be achieved throughout the disk...
Aluminum alloys are popular in aerospace and automotive industries because of their relatively high strength-to-weight ratio. The study of enhancing aluminum’s mechanical properties through grain refinement is especially important. One such technique is High-Pressure Torsion processing (HPT), which leads to significant grain size refinement and enhances mechanical properties like ductility...
Processing of metals through the application of high-pressure torsion (HPT) provides significant grain refinement in bulk metals at ambient temperatures. The ultrafine-grained (UFG) materials processed by HPT generally demonstrate the superior physical and mechanical characteristics. For utilizing the benefit of HPT, the feasibility of conventional HPT processing was demonstrated recently...
Aluminum and copper and their alloys have been widely used due to relatively high strength-to-weight ratios compared with conventional steels. Processing of these alloys is typically conducted at high temperatures over extended time periods. High-pressure torsion (HPT) is a promising processing technique for introducing significant grain refinement leading to excellent...
