Revisiting Stability Criteria in Ball‐Milled High‐Entropy Alloys: Do Hume–Rothery and Thermodynamic Rules Equally Apply?

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

Advanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Achieving high energy density and high power density with pseudocapacitive materials

Nature Reviews Materials, 2019
Batteries and supercapacitors serve as the basis for electrochemical energy-storage devices. Although both rely on electrochemical processes, their charge-storage mechanisms are dissimilar, giving rise to different energy and power densities. Pseudocapacitive materials store charge through battery-like redox reactions but at fast rates comparable to ...

High power density thin film resistors

1975 EIC 12th Electrical/Electronics Insulation Conference, 1975
Untrimmed Ni-Cr resistors on glazed alumina substrates, hermetically sealed in a dry nitrogen atmosphere, survive and remain stable when subjected to power densities greater 2000 W/in2. Large (>7 × 10−4in 2 ) resistors with standard top-hat trimming fail at less than 1000 W/in2 due to hot spots, however, a change in trim line configuration results in ...
