Abstract High-entropy alloys (HEAs), as a new class of materials, are nearly equiatomic and
multi-element systems, which can crystallize as a single phase or multi-phases. Most of the …

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 …

This is the first of three overviews on failure of metals. Here, brittle and ductile failure under
monotonic loadings are addressed within the context of the local approach to fracture. In this …

Sliding friction is one of the oldest problems in physics and certainly one of the most
important from a practical point of view. The ability to produce durable low-friction surfaces …

The localisation of plastic flow due to dynamic strain ageing is evaluated taking into account
transient behaviour associated with the time dependence of the solute composition at …

Flow stress and work hardening behaviors, as two important aspects of mechanical
behaviors, have been studied extensively and their interpretation for the case of pure metals …

A non-contact strain measurement technique, based on digital image correlation (DIC)
analysis, has been utilized in order to observe Portevin–Le Chatelier (PLC) band behaviour …

Abstract The Portevin-Le Chatelier (PLC) effect is a manifestation of macroscopic scale non-
uniformities which have their origins on a microstructural level. The coordination of …

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

Local strain hardening in a cross-section of a deforming crystal has been related to the
evolutionary behavior of the coupled densities of the mobile and (relatively immobile) forest …
