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

Critical metals in discarded electronics

, 2016
Recycling of waste from electrical and electronic equipment (WEEE) traditionally focuses on large quantities of waste materials such as plastics. However, some product groups in the WEEE contain hidden treasures in the form of critical metals. This project assesses the critical metals’ waste handling as part of five selected product groups, in the ...

Evaluation of the Potential of Laser Shock Peening Compared with Cold Expansion for Improving Fatigue Resistance of Riveted Lap Joints of Aerospace Grade 7175 Al Alloy

Advanced Engineering Materials, EarlyView.
This study investigates laser shock peening for enhancing fatigue performance of riveted aerospace aluminum joints. A comparative approach with cold expansion combines fatigue testing and synchrotron X‐ray methods. Integrating mechanical testing with residual stress and strain characterization provides insights into how different treatments affect the ...

Polynomial modelling of high-quality yet incomplete rare earth element data sets and a holistic assessment of REE anomalies

Scientific Reports
Rare earth elements (REEs) are powerful proxies used in many (bio-)geochemical studies. Interpretation of REE data relies on normalised REE patterns and anomaly quantification, and requires complete data.

Effects of grinding media on the surface roughness and flotation kinetics of lepidolite

Results in Surfaces and Interfaces
In this study, effects of ball and rod grinding on the surface roughness and flotation kinetics of lepidolite were investigated. Flotation tests revealed that the rod ground products had higher flotation efficiency than the ball ground products.

Adjustment of Coatings Morphology and Particle Distribution of Layered Silicates by Freeze‐Drying for Improved Gas Barriers

Advanced Engineering Materials, EarlyView.
Freeze‐drying of layered silicate is the key to get coatings with superior gas barrier. Freeze‐drying of layered silicates modified with dodecylamine (DDA) is a highly effective technique for the preparation of barrier pigments that significantly mitigate the permeation of oxygen, water vapor, and hydrogen through polymer films containing these ...

Assessing the Criticality of Metals [PDF]

, 2013
Today’s technology employs virtually the entire periodic table. The stocks and flows of the major metals, essentially unknown a decade ago, are now reasonably well quantified. Those cycles can be used to generate on overview of societal metal use. A key issue is whether scarcity implies long-term shortages or unavailability.

Is Young's Modulus a Critical Coating Property Determining Fouling‐Release Performance of Marine Coatings?

Advanced Engineering Materials, EarlyView.
The release of foulers from protective marine coatings is determined by several interrelated material properties, including the strength of Young's modulus, the flexibility of chain segments, the surface free energy, and the magnitude of hydrodynamic stress.
