Aspects of serrated flow in aluminium alloys
… of the work, and at strain rates such that serrated tensile test curves were manifest. The evolution of microstructural features of the deformation was evaluated utilising both optical and electron microscopy. Surface deformation features, including the formation of both type A and type B …

Elevated temperature mechanical properties of line pipe steels
… the internal/effective stress components of the flow stress and apparent activation volumes. Torsional pendulum experiments were performed to measure internal friction carbon Snoek peak heights related to the free interstitial concentrations in bcc ferrite. Microstructural changes after tensile …

The influence of nickel-nitrogen ratio on the deformation behaviour of austenitic stainless steels
… extent in martensite. Furthermore, pronounced serrated flow is identified in the experimental alloys when deformed at 60°C, whereas the behaviour is absent in AISI 301. Both these factors need to be considered when taking into account the formability of the experimental alloys. This study …

Phase stability and the Portevin-Le Chatelier effect in Cr-Mn-Fe-Co-Ni High-Entropy Alloys
… associated with serrations in the materials flow curve and the localisation of strain into discrete bands. Serrated flow has been observed in several HEAs but the associated strain localisation behaviour has not yet been reported, so it is uncertain whether this behaviour is similar to the …
