The accuracy and efficiency of electronic-structure methods to understand, predict and
design the properties of materials has driven a new paradigm in research. Simulations can …

This review summarizes recent advances in the area of tribology based on the outcome of a
Lorentz Center workshop surveying various physical, chemical and mechanical phenomena …

Rapid solidification cellular structures are known to play a crucial role in helping achieve
high strength and high ductility in 316L austenitic stainless steels fabricated by laser powder …

Continuous innovations in design of advanced structural steels are essential for future
progress in manufacturing, automotive and construction industries. Events taking place at …

Dislocation glide is a general deformation mode, governing the strength of metals. Via
discrete dislocation dynamics and molecular dynamics simulations, we investigate the strain …

Grain boundaries (GBs) are central defects for describing polycrystalline materials, and
playing major role in a wide-range of physical properties of polycrystals. Control over GB …

Ordinarily, the strength and plasticity properties of a metal are defined by dislocations—line
defects in the crystal lattice whose motion results in material slippage along lattice planes …

The mechanical behavior of nanolaminates is dominated by interfaces that act as sources,
barriers, and preferred sites for storage and dynamic recovery of glide dislocations. In this …

Size-affected dislocation-mediated plasticity is important in a wide range of materials and
technologies. Here we develop a generalized size-dependent dislocation-based model that …

Slip in face centred cubic (fcc) metals is well documented to occur on {111} planes in< 110>
directions. In body centred cubic (bcc) metals, the slip direction is also well established to …
