Influence of Heat Treatment on Microstructure and Mechanical Properties at Elevated Temperatures of Nonweldable Ni‐Based Alloy Printed by Fused Filament Fabrication

Advanced Engineering Materials, EarlyView.
The fused filament‐fabricated MAR‐M247 alloy without hot isostatic pressing shows the lowest porosity of 4%. Heat treatment at 1220 °C produces coarse precipitates and carbides. Specimens heat‐treated at 1220 °C exhibit higher tensile strength (683 MPa) and elongation (10%) at room temperature.

Investigation of Oxide Dispersion Strengthening Effect on the Strength of Diffusion‐Bonded AISI304 Parts

Advanced Engineering Materials, EarlyView.
Experiments for reinforcing the diffusion bonding plane by the oxide dispersion strengthening effect are presented. Small ceramic particles (0.5 and 50 μm, respectively) are incorporated. Furthermore, ceramic particles help to penetrate stable passivation layers, enabling atomic diffusion across bonding planes. Since a ceramic–metallic interface cannot

Toughness of Confined Auxetic Foams

Advanced Engineering Materials, EarlyView.
Auxetic (negative Poisson's ratio) materials offer benefits such as impact mitigation, thermal insulation, vibration damping, and reduced shear strain, although their fracture mechanics are largely unexplored. This study investigates damage initiation and propagation in confined re‐entrant auxetic foams from polyurethane via experimental ...

Multimodal Characterization Method for Metamaterials with Tunable Mechanical Stiffness and Electrical Resistivity

Advanced Engineering Materials, EarlyView.
This study presents a multimodal characterization method for a prototype metamaterial model structure that features four distinct states of mechanical stiffness and electrical resistivity. Through simulations and experiments, it uncovers insights into the structural behavior, the correlation between changes in electrical resistivity and mechanical ...

On the Deformation Behavior of Metastable CrMnNi Steels Processed by Directed Energy Deposition in Different Temperature Regimes

Advanced Engineering Materials, EarlyView.
In the present study, metastable CrMnNi steels with varying chemical compositions and a concomitantly altered stacking fault energy are processed via directed energy deposition and afterwards tested via tensile tests at different temperatures. The present study shows the influence of the manufacturing process on the elemental deformation mechanisms for

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

Advanced 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 Hot Isostatic Pressing on Microstructure Evolution and Creep Performance of Powder Bed Fusion–Laser Beam Processed CM247LC

Advanced Engineering Materials, EarlyView.
The influence of Hot Isostatic Pressing (HIP) temperature on the microstructure and creep performance of powder bed fusion–laser beam processed CM247LC superalloy is investigated. Grain growth and γ’ precipitate evolution are characterized following HIP at varying temperatures.
