Development of Aluminum Scandium Alloys for Hydrogen Storage Valves

open access: yesAdvanced Engineering Materials, EarlyView.
Different aluminum alloy series and various aluminum‐scandium alloys with differing Sc and Zr levels are evaluated for use in hydrogen storage valve production. The alloys undergo hardness testing, optical microscopy, and tensile strength analysis, with hardening behavior studied under varying conditions.

Performance Comparison of Surface Sensitizers for Diode Laser Powder Bed Fusion of Polyamide 12

open access: yesAdvanced Engineering Materials, EarlyView.
Laser‐generated nanoparticles transform standard PA12 powders into high‐performance, dye‐free feedstocks for diode laser 3D printing. Despite identical absorbance at 808 nm, CuS, LaB6, and CB coatings reveal striking differences in fusion and strength—unlocking new design space for recyclable, industrial‐grade polymers.

CALPHAD‐Guided Prediction and Interpretation of Phase Formation in Ta–Mo–Cr–Ti–Al Refractory High‐Entropy Alloys

open access: yesAdvanced Engineering Materials, EarlyView.
This study designs Ta–Mo–Cr–Ti–Al refractory high‐entropy alloys with a disordered body‐centered‐cubic A2 crystal structure aiming for improved ductility, lower density, and oxidation resistance. Four alloy compositions are identified by thermodynamic calculations.

A Simulative Evaluation of Triply Periodic Minimal Surface Structures in the Context of Elastocaloric Applications

open access: yesAdvanced Engineering Materials, EarlyView.
A simulative evaluation of triply periodic minimal surface (TPMS) structures for an elastocaloric application under compressive load is performed. For the evaluation of the structure's performance, surface/volume ratio, generated heat and invested mechanical work are taken into account and are compared to a tube as a reference specimen.

Impact of Various Rotary Friction Welding Process Parameters on the Mechanical Properties of a Steel–Aluminum Joint

open access: yesAdvanced Engineering Materials, EarlyView.
Rotary friction welding of steel E355 and the aluminum alloy EN AW‐6082 can lead to the formation of brittle intermetallic phases. The primary process parameters are varied in order to determine their influence on this intermetallic phase formation and the resulting mechanical properties.
