The cross-slip process of a screw dislocation in model Ni (Al) random solid solution is
studied using the climbing image nudged elastic band method with an embedded-atom …

During the next decade, fundamental research on metals and metallic nanostructures
(MMNs) has the potential to continue transforming metals science into innovative materials …

This work examines binary dislocation interactions, junction formation and junction strengths
in hexagonal close-packed (hcp) crystals. Through a line-tension model and dislocation …

An introduction to creep and its main characterstics are given. Stationary creep has been
studied extensively in the literature. Stationary creep is a result of a balance between work …

The structural stability of vacancy-hydrogen complexes at the γ′/γ interface in nickel-based
single-crystal superalloy is accessed mainly by calculating the activation energies …

The operation mechanism of single cross slip multiplication (SCSM) is investigated by
studying the response of one dislocation loop expanding in face-centered-cubic (FCC) …

Materials deform, though different materials do not deform in the same way. They should not
be expected to, as they can have very different underlying structures. In ductile metals …

Self-organized dislocation structures in deforming metals have a strong influence on the
mechanical response of metals. However, accurate prediction of these patterns remains a …

Plastic deformation of classical crystalline materials is mostly dominated by dislocations and
their mutual interactions. In nanocrystalline (nc) metals, different grain boundary …

The proposed model is inspired by Brown's suggestion that the saturation stress in cycling is
controlled by the stress required to separate two screw dislocations of opposite signs, which …
