Additive Manufacturing of Highly Alloyed Aluminum–Lithium

Advanced 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.

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

Advanced 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 ...

Mechanical and Microstructural Effects of ZrO2 Nanoparticles in Fe20Cr Oxide Dispersion‐Strengthened Alloys Processed by Laser Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
The influence of oxide nanoparticle synthesis route and concentration on microstructure and high‐temperature performance of additively manufactured oxide dispersion‐strengthened steels is investigated. Comparing laser‐generated and chemically synthesized ZrO2 nanoparticles, the study reveals how dispersion quality, crystal structure and particle size ...

Quality Enhancement of Laser Powder‐Bed Fusion Parts by Acoustically Assisted Additive Manufacturing by Laser Powder‐Bed Fusion and its Application to Lattice Structures

Advanced Engineering Materials, EarlyView.
Additive manufacturing technologies like laser powder‐bed fusion offer great design freedom and individualization of products down to a batch size of one. However, parts fabricated with this technology suffer from poor quality. Acoustic assistance during the build process can minimize these drawbacks.
