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

open access: yesAdvanced 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

open access: yesAdvanced 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

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

open access: yesAdvanced 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
