Bulk nanocrystalline alloys usually possess enhanced properties than their coarse-grained counterparts. Here, first-principles calculations and aberration-corrected transmission electron microscope (TEM) were employed to investigate the atomic-scale

The deformation characteristics of ultrafine grained (UFG) iron, ultrafine lamellar (UFL) pearlite and nanolamellar (NL) pearlite were investigated using in situ synchrotron compression tests. The direct measurement of the peak position and peak widt

Initially micrometer-sized powder blends of different compositions (Cu-6at%Ag, Cu-37 at%Ag and Cu-84 at%Ag corresponding to Cu-9vol%Ag, Cu-46 vol%Ag and Cu-89 vol%Ag) were deformed by high-pressure torsion for varying applied strain and temperature i

Ag–Cu alloys of two different initial microstructures—a cast eutectic alloy (AgCu-E) and an equivolume Ag–Cu powder mixture (AgCu-P)—were deformed by high-pressure torsion. The codeformation of Ag and Cu grains led to uniform refinement and a

Nanocrystalline materials tend to have an inferior fatigue crack-growth behavior, compared to coarser-grained counterparts, due to the loss of crack-closure effects. Strategies to mitigate this effect are widely unknown as grain-refinement changes th

The application of duplex steels is constantly increasing due to their excellent combination of high strength and fracture toughness complemented with superior resistance to localized chemical corrosion and stress corrosion. Since ultrafine-grained a

The aim of this study is to show that new types of bulk metallic glass composites (BMGCs) can be produced via severe plastic deformation (SPD). The initial materials are mixtures of a Zr-metallic glass (MG) and crystalline Cu powders that were mixed

In this study, different Cu–Ag alloys (Cu-10/25/50/75/90 wt%Ag) are produced by powder consolidation and subsequent high-pressure torsion processing. The microstructural evolution of the material state is investigated by SEM and TEM. Additionally,
