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 …

The strengthening of metals by a variety of means has been of interest over much of history.
However, the elucidation of the actual mechanisms involved in the processes of alloying and …

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 …

Dynamic strain ageing (DSA) is the phenomenon in which solute atoms diffuse around
dislocations and retard dislocation motion, leading to negative strain-rate sensitivity (nSRS) …

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

Dynamic strain aging arises from the interaction between solute atoms and matrix
dislocations in strained metallic alloy. It initiates jerky dislocation motion and abrupt …

By employing the dynamic digital speckle pattern interferometry (DSPI) technique, three
types of Portevin–Le Chatelier (PLC) effects are investigated systematically, with emphasis …

In this study, the strain-hardening and fracture behavior of high manganese austenitic
twinning induced plasticity (TWIP) steel at temperatures ranging from 123 K to 773 K were …

High entropy alloys (HEAs) are a new kind of basic materials with excellent properties,
which can be used in extreme service environment. In this paper, high temperature tensile …
