Comparative Study of Experimental Methods for Measuring Thermal Properties of 100Cr6 Steel Powders

Advanced Engineering Materials, EarlyView.
This study investigates the thermal properties of 100Cr6 steel in both bulk and powder forms. Measuring the very low thermal conductivity typically exhibited by powders poses significant challenges. To address this, two novel measurement techniques—temperature gradient and finite laser pulse response—are introduced and evaluated by comparison with the ...

Ag Cluster‐Modified K0.5Na0.5NbO3 Piezocatalyst for Enhanced Electrochemical Dinitrogen Reduction Reaction

Advanced Engineering Materials, EarlyView.
Ag cluster‐modified K0.5Na0.5NbO3 acts as an efficient piezocatalyst for electrochemical N2 reduction, enhanced by built‐in electric fields under mechanical actuation. Comparative studies between static and actuated electrodes reveal improved performance under dynamic conditions.

Laboratory‐Scale Procedure for Evaluating the Flux Efficiency on Melt Cleanliness and Tensile Properties of Recycled Aluminum Alloys

Advanced Engineering Materials, EarlyView.
A laboratory‐scale procedure is developed to evaluate the efficiency of melt‐cleaning and drossing fluxes during aluminium alloy recycling, studying their effects on melt cleanliness and tensile properties of secondary foundry alloys. This work provides a practical tool for foundries and aluminium refiners to assess the efficiency of salt fluxes in ...

Mechanical Properties of Different Austenitic High‐Nitrogen Steel Grades Produced by Powder Mixtures

Advanced Engineering Materials, EarlyView.
The effect of nitrogen content on the mechanical properties of austenitic stainless steels is investigated using tailored powder metallurgical processing. Different PM routes, including additive manufacturing, enable controlled nitrogen uptake and complex geometries.

Improving Surface Quality of Titanium Electrodeposition from a Deep Eutectic Solvent with Organic and Inorganic Additives

Advanced Engineering Materials, EarlyView.
Herein, the electroplating of titanium from an organic solvent, ethaline, is shown. Polymer additives are shown to smooth the roughness of the film, and small molecule additives are shown to produce a near‐mirror finish to the deposited metal. Titanium electroreduction is desired for a variety of medical, electronic, and bonding applications but has ...
