Abstract Dynamic Strain Ageing (DSA) has reached widespread acceptance since its
proposal in the 1940's as the mechanism behind the Portevin-Le Chatelier effect in ferritic …

Serration and noise behaviors in plastically deforming solids are related to avalanches of
deformation processes. In the stress-strain curves, the serration characteristics are visible as …

Achieving high mechanical strength and ductility in age-hardenable Al7000 series (Al–Zn–
Mg) alloys fabricated by selective laser melting (SLM) remains challenging. Here, we show …

Considerable studies on metal selective laser melting (SLM) have proved the necessity to
refine microstructure parts fabricated by SLM in order to eliminate property anisotropy, hot …

Abstract The Portevin–Le Chatelier (PLC) effect manifests itself as an unstable plastic flow
during tensile tests of some dilute alloys under certain regimes of strain rate and …

The development of wire arc additive manufacturing (WAAM) provides a new solution for
manufacturing aluminum alloy (AA) components used in lightweight mobile heat storage …

This work investigated the influence of laser scan strategy, which essentially determines the
molten pool path, on microstructure evolution, residual stress and mechanical properties of …

Laser melting deposition with WC addition has been developed to fabricate high-strength
CrMnFeCoNi-based high-entropy alloys-based composites. By this technique, a …

Abstract High-strength CrMnFeCoNi-based High Entropy Alloys have been developed by
laser melting deposition, in which tensile properties of them could be adjusted by controlling …

The well-known mechanisms of interaction between precipitates and dislocations are
shearing (for shearable precipitates) and bypassing mechanisms (for nonshearable …
