Among metal additive manufacturing technologies, additive friction stir deposition stands out
for its ability to create freeform and fully-dense structures without melting and solidification …

Twins have been proven to greatly enhance the hardness, toughness, thermal stability, and
wear resistance of materials. However, the formation of twins in transition nitride ceramics is …

Alloying technology usually improves the mechanical properties of alloys; however, the high
cost of alloying elements limits their wider applicability to conventional cast aluminium …

Generalized stacking fault energies of aluminum alloys were calculated using density
functional theory. Stacking fault energy of aluminum alloys was correlated with the d …

Abstract Nanostructured crystalline Al/amorphous AlN multilayer films with a wide layer
thickness (h) range from∼ 10 nm up to∼ 200 nm were prepared by using magnetron …

The performance of the material can be significantly improved by introducing stacking faults
and nanotwins. However, introducing high-density stacking faults and twins into Al remains …

The extensive heat input during welding can generally disrupt the meticulously crafted
microstructure of the Al alloy substrate, leading to a marked decrease in the mechanical …

Dislocation core dominates dislocation mobility and mechanical properties of crystalline
solids. To date, a complete landscape for describing dislocation with narrow core in metals …

Stacking-fault energy (SFE) is a critical parameter that influences plastic deformation of Cu
alloys. Here, the SFEs of Cu solid solutions at various temperatures and solute …

Bulk nanocrystalline alloys usually possess enhanced properties than their coarse-grained
counterparts. Here, first-principles calculations and aberration-corrected transmission …
