This work elucidates the dependence of operating stress of persistent slip bands (PSB) on the channel width and wall dislocation density. Using Cu as a model system and molecular dynamics as the main investigative tool, a new length scale effect, nam

Taking the well-understood Cu-Ni {111} semi-coherent interface as a prototype, we demonstrate an important, yet long-been-overlooked, size effect on the properties of terraced interfaces — i.e. the facet length scale effect. Interfacial facets are

Fatigue cracks often initiate from the surface extrusion/intrusions formed due to the operation of persistent slip bands (PSBs). Suppression of these surface topographical features by hard surface coatings can significantly extend fatigue lives under

Quantitative assessment of the adhesion strength of ceramic hard coatings on substrates is a subject of great technological and scientific relevance, the achievement of which has proven difficult over the past two decades. Here we show that a micro-p

Mechanical and fatigue performance of γ-γ′ Ni-base superalloys are strongly affected by the antiphase boundary energy (APBE) of the γ′ precipitates which, in turn, is dictated by the alloy's composition. Due to the multicomponent character of
