There are several facets of aluminum when it comes to sustainability. While it helps to save
fuel due to its low density, producing it from ores is very energy-intensive. Recycling it shifts …

Abstract High-entropy alloys (HEAs), also known as multi-principal element alloys or multi-
component alloys, have been the subject of numerous investigations since they were first …

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 …

A high strength Al-5024 alloy containing Sc and Zr with a bi-modal microstructure consisting
of fine equiaxed and coarse columnar grains was successfully fabricated by laser powder …

Traditionally 4xxx casting alloys are used for the additive manufacturing of structurally
optimised lightweight parts in space, aerospace and automotive. However, for such …

Addition of a small amount of Ca improves the ductility of Mg alloys. However, the
mechanism underlying this effect is not well understood. In this work, tensile testing of an …

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 …

The microstructure and phase composition in selective laser melted (SLM) Ti-6Al-4V plays a
key role for its mechanical performance. The microstructure evolution in SLM Ti-6Al-4V was …

We report on the strengthening and strain hardening mechanisms in an aged high-Mn
lightweight steel (Fe-30.4 Mn-8Al-1.2 C, wt.%) studied by electron channeling contrast …

This paper focuses on experimental investigations on the kinematic and thermal aspects of
the propagative plastic instabilities, namely Lüders band and Portevin–Le Châtelier (PLC) …
