Grain refinement and arrangement is an effective strategy to enhance tensile and fatigue
properties of key metallic components. Laser shock peening (LSP) is one of surface severe …

Abstract Bulk nanostructured (ns)/ultrafine-grained (UFG) metallic materials possess very
high strength, making them attractive for high strength, lightweight and energy efficient …

Dislocation cores, the regions in the immediate vicinity of dislocation lines, control a number
of properties such as dislocation mobility, cross-slip and short-range interactions with other …

Al-Mg based alloys are known to experience dynamic strain aging (DSA) at room
temperature, which is often associated with the diffusion of mobile Mg atoms to dislocation …

Al-Mg alloys are a series of low cost and low density Al alloys, which show remarkable
strengthening during deformation. In this work, study of commercial purity Al, Al-0.5 Mg and …

In this study, the development of the microstructure and crystallographic texture during
friction stir welding (FSW) of AA2024 and AA6061 dissimilar joint was investigated. Electron …

As the major strengthening phase, T 1 precipitates contribute over 60% of strength to the
advanced Al-Cu-Li alloys. Its nucleation is the first critical step in determining how many …

Abstract Architecture design enables multi-mechanism coordination of strengthening and
toughening to overcome the strength-ductility trade-off in particulate reinforced metal matrix …

The generalized stacking fault energies of magnesium and their alloys have been calculated
using density functional theory. It is shown that the deformation tendency caused by partial …
