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 Iron‐Aluminide‐Like Phase Composition in Complex Concentrated Fe32Cu12Ni11Ti16Al29 Alloy

Advanced Engineering Materials, EarlyView.
This work reveals the phase composition and quantitative morphology analysis of precipitation‐hardened Fe32Cu12Ni11Ti16Al29 complex‐concentrated alloy. The precipitates are shown to have a high coherency. Morphology transition between sphere, cuboidal, and elongated morphology is observed. Finally, the overaging behavior is captured using microhardness.

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 ...

Reactive Interaction and Wetting of Fe‐ and Mn‐Containing, Secondary AlSi Alloys with Manganese Oxide Ceramic Filter Material for Fe Removal

Advanced Engineering Materials, EarlyView.
Fe‐ and Mn‐containing AlSi alloys undergo aluminothermic reaction with Mn oxide in sessile‐drop and crucible experiments forming poor‐wetting Al2O3 while Mn enriches in the alloy. Primary Fe‐containing particles are preferentially attached to the Mn oxide.

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.
