Metals, ceramics, polymers, and composites have been employed in joint arthroplasty with
ever increasing success since the 1960s. New materials to repair or replace human skeletal …

The review focuses on the supersaturation process of immiscible elements induced by high‐
pressure torsion deformation. A variety of investigated material systems offers the systematic …

Fully-dense bulk CoCrFeMnNi high entropy alloy (HEA) has been obtained by high-
pressure torsion (HPT) deformation. Elemental, micrometer sized powders were …

Severe plastic deformation (SPD) always leads to the strong grain refinement in the
materials. Logically, in two-and multiphase alloys SPD has to cause the fragmentation and …

Heavy plastic shear deformation at relatively low homologous temperatures is called high-
pressure torsion (HPT) deformation, which is one method of severe plastic deformation …

Sliding wear-induced nanolayering and its positive impact on wear resistance have been
observed in conventional binary alloys with a matrix of high stacking fault energy (SFE), but …

Abstract Nanostructured Cu–Ta alloys have shown promise as high-strength nanocrystalline
materials in part due to their limited grain growth at high temperatures. In the present study …

Sliding friction of metallic materials results in severe plastic deformation of the contacting
surfaces. While plastic deformation is generally considered detrimental, as it leads to …

The tradeoff between strength and ductility has long been identified as the 'Achilles' heel'of
the mechanical properties in engineering applications. Metal hybrids processed by severe …

Abstract Bulk nanolayered Cu/Nb composites fabricated by accumulative roll bonding
(ARB), leading to a nominal layer thickness of 18 nm, were subjected to large shear …
