Effect of the over-ageing treatment on the mechanical properties of AA2024 aluminum alloy. [PDF]

open access: yes, 2012
The evolution of the hardness of the over-ageing AA2024 alloy scale was followed by measurements of Vickers hardness. The nanoindentation is adapted to the determination of elastoplastic properties (hardness and Young’s modulus) of the matrix and also of

Ba–Ni–Ge Clathrate Transformation Maximizes Active Site Utilization of Nickel for Enhanced Oxygen Evolution Performance

open access: yesAngewandte Chemie International Edition, EarlyView.
For the first time, this study demonstrates a huge advantage of the clathrate Ba–Ni–Ge intermetallic bulk over metallic nickel as a high‐performance alkaline OER precatalyst. It displays remarkable activity and stability under high current densities, facilitated by a thorough reconstruction process that yields a porous and defective NiOOH ...

Microstructural characterisation and thermal stability of an Mg-Al-Sr alloy prepared by rheo-diecasting [PDF]

open access: yes, 2007
A commercial Mg-6Al-2Sr (AJ62) alloy has been prepared by a semisolid rheo-diecasting (RDC) process. The microstructure of the RDC alloy exhibits typical semisolid solidification features, i.e., 8.4 vol% primary α-Mg globules (23 μm in diameter), formed ...

Synthesis of Molecular Organo‐f‐Element‐Polyphosphides with Non‐Classical Divalent Lanthanide Precursors

open access: yesAngewandte Chemie International Edition, Accepted Article.
The coordination and functionalization of white phosphorus (P4) by transition metal and main group element compounds has led to a great variety of polyphosphides. However, larger polyphosphides of the rare‐earth elements are elusive. In this study, we report the synthesis and full characterization of the largest polyphosphides of the f‐elements, [K(18 ...

Role of Silicon as Structural Stabilizer and Redox‐Active Element in Multicomponent (Sn, Sb, Fe, Si) Alloy Electrodes for Na‐Ion Batteries

open access: yesBatteries &Supercaps, EarlyView.
Multicomponent alloys based on Sn, Sb, Si, and Fe are prepared via ball milling and tested as Na‐ion battery electrodes. Despite its promise as a high‐capacity material, Si is found to be redox‐inactive. However, it acts as a structure stabilizer in multicomponent alloys, enabling stable cycling.Metal alloys are attractive electrode materials for ...
