Direct Consolidation of Copper–Graphene Composite by Rotary Swaging

open access: yesAdvanced Engineering Materials, EarlyView.
The applicability of the rotary swaging method for preparation of electroconductive copper–graphene composite by direct consolidation of powders is proven. The consolidated material features advantageous microstructure featuring fine grains and twins, with homogeneous distribution of graphene, primarily along the twin boundaries, which contribute to ...

Laser Additive Manufacturing of Oxide‐Dispersion‐Strengthened Steels: A Simulation‐Based Comparison Between Powder Bed Fusion and Direct Energy Deposition

open access: yesAdvanced Engineering Materials, EarlyView.
Controlling the size and distribution of dispersoids is essential for optimizing the performance of oxide‐dispersion‐strengthened steels. This study focuses on nanoparticle dispersion and agglomeration during laser additive manufacturing of Fe20Cr alloy reinforced with ZrO 2 nanoparticles. Utilizing multiphysics phase‐field simulations and nanoparticle

Additive Manufacturing of Highly Alloyed Aluminum–Lithium

open access: yesAdvanced Engineering Materials, EarlyView.
Al–Li alloys, promising for future lightweight constructions due to their low density and high stiffness, are limited to 9 at% lithium in commercial forms because of segregation issues. To overcome this traditional limitation, powder bed fusion with an ultrashort pulse laser is used.

Dislocation avalanche correlations

open access: yes, 2003
Recently, mechanical tests on ice as well as dislocation dynamics simulations have revealed that plastic flow displays a scale-free intermittent dynamics characterized by dislocation avalanches with a power law distribution of amplitudes.

The Effect of Elastic–Plastic Mismatch and Interface Proximity on the Fracture Toughness of Ti‐TiN Thin Films

open access: yesAdvanced Engineering Materials, EarlyView.
Multilayering of TiN film with metallic Ti film is adopted to enhance the fracture resistance of TiN thin films. Plastic dissipation within Ti with process zone size of ≈250 nm, along with elastic–plastic mismatch driven changes to crack driving force enhances the crack growth resistance by ten times, enabling physics informed design of optimized ...
