Preparation and Thermal Modification of Disentangled Ultrahigh‐Molecular‐Weight Polyethylene Particles for Powder‐Based Additive Manufacturing

Advanced Engineering Materials, EarlyView.
Ultrahigh‐molecular‐weight polyethylene powders (<≈40 μm) with a bulk density of 260 g L−1 are prepared from a silica supported bisimine pyridine iron catalyst. The nascent product is disentangled and can be thermally densified without loss of its low viscosity.

Investigation of 3D Wave Propagation in Foam‐Core Functionally Graded Material Magneto‐Piezoelectric Smart Nanoplates

Advanced Engineering Materials, EarlyView.
This study reveals how wave propagation in FG‐MEE nanoplates can be tuned via material gradients, porosity, and external fields. Using NSGT and Hamilton's principle, analytical solutions capture key dispersion behaviors. Findings highlight the potential of smart nanoplates for adaptive control in high‐performance applications like sonar and aerospace ...

Combining Metal Additive Manufacturing and Casting Technology: High Performance Cooling Channels for Electric Powertrain Components

Advanced Engineering Materials, EarlyView.
When realized as inserts in high‐pressure die casting, aluminum cooling channels for electric powertrain components and similar applications typically require a stabilizing filler to survive the process. The present study investigates relinquishing this filler using additively manufactured inserts promising performance improvements.

Finite Element Modeling of Residual Stress Formation during Nanosecond Laser Ablation of Stainless Steel

Advanced Engineering Materials, EarlyView.
This article investigates residual stress formation during single‐spot nanosecond laser ablation of stainless steel. Experimental validation and a parametric study using finite element simulations are employed to analyze thermal effects, ablation dynamics, and stress evolution.
