Simulation‐Based Analysis of Insert Pull‐Out in Nickel‐Polyurethane Hybrid Foams Using CT‐Derived Geometries

Advanced Engineering Materials, EarlyView.
CT‐based finite element simulations combined with in situ X‐ray computed tomography are used to analyze insert pull‐out in nickel‐coated polymer foams. Despite variations in material parameters, deformation consistently concentrates within a narrow annular region around the insert.

Influence of high -temperature powder pre-oxidation on the deposition efficiency and the mechanical properties of solid-state cold spray additive-manufactured aluminium deposits

Virtual and Physical Prototyping
Cold spraying (CS), as a solid-state additive manufacturing technique, offers a unique metallurgical process in metal deposition. This work focuses on Al powder properties, particularly particle size and oxide film, which influence deposition efficiency (

Influence of TiC and TiN Ceramic Reinforcements on the Microstructure, Thermal Expansion Behavior, and Tensile Properties of Invar 36 Manufactured by Laser Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
This study examines Invar composites reinforced with titanium carbide (TiC) and titanium nitride (TiN) using laser powder bed fusion (LPBF). It presents the influence of reinforcements on microstructure, tensile properties, and thermal expansion. Results show that TiC effectively strengthens Invar while maintaining low thermal expansion, whereas TiN ...

Thermodynamics guided design and processing of a WC/HEA cermet tool for high temperature friction stir welding

Materials & Design
Friction stir welding (FSW) of high temperature materials such as ferrous alloys, Ti-alloys, and Ni-alloys is challenging due to the high costs, short tool lives, and limited availability of tool materials.

Cryogenic Deformation Behavior of TiAl and Insights Into Embrittlement After High‐Temperature Exposure Combined With Secondary Ion Mass Spectroscopy of Near Surface Chemistry

Advanced Engineering Materials, EarlyView.
Near‐surface deuterium enrichment profiles for different microstructural types of TiAl after exposure at 700 °C in a heavy water‐containing environment. The deuterium levels are significantly higher than expected from natural occurrence, indicating that the heavy water dissociated during the exposure treatment and entered the specimens.

Friction and Wear of Automotive Friction Materials

, 2020
The present work discusses the tribological performance of friction composites reinforced by corn and palm fibres at continuous and starting – stopping tests aiming to provide specific relationship between the performances of the two tests. In the friction composites, asbestos is replaced by the corn and palm leaf fibres.

Enhancement of the Through‐Thickness Electrical Conductivity of Carbon‐Fiber‐Reinforced Plastics Using Large Graphite Particles

Advanced Engineering Materials, EarlyView.
To enhance through‐thickness conductivity without sacrificing impregnation, large spherical graphite particles are intentionally employed in a low‐viscosity resin. Unlike finer conductive fillers, these particles remain outside the fiber bundles and accumulate in resin‐rich interlaminar regions during molding.
