Effect of Annealing Temperature on Microstructure and Dry‐Sliding Behavior of Powder Bed Fusion–Laser Beam Ti6Al2Sn4Zr6Mo Alloy

open access: yesAdvanced Engineering Materials, EarlyView.
Heat treatment parameters critically affect the wear resistance of powder bed fusion–laser beam (PBF‐LB)‐produced Ti–6Al–2Sn–4Zr–6Mo alloy. This study found that optimizing annealing temperature allows to obtain a tailored microstructure, which enhances the dry‐sliding behavior by forming a stable and functional mechanically mixed layer (MML), ensuring

Heterostructure‐Specific Toughening Mechanisms in Metallic Laminates

open access: yesAdvanced Engineering Materials, EarlyView.
This study highlights how various aspects of the heterostructural design of metallic laminates can be specifically tailored to achieve improved fracture resistance for damage‐tolerant designs of cyclically stressed components. Based on results from in situ fatigue crack growth tests, a comprehensive overview of the formation and development of ...

Direct Recycling of Cold Work Tool Steel Swarf into New Cutting Disks via Field‐Assisted Sintering

open access: yesAdvanced Engineering Materials, EarlyView.
Through a sintering method known as field‐assisted sintering technology/spark plasma sintering, cold work tool steel swarf can be directly recycled into new cutting disks. This method is capable of densifying the unconventional powder morphology of swarf, and it can also seal grinding contaminants, such as Al2O3, into the steel matrix.

Toughness and spectrum of a graph

open access: yesLinear Algebra and its Applications, 1995
The author proves the following theorem: Let \(G\) be a connected non- complete regular graph of valency \(d\) and let \(\lambda\) be the maximum of the absolute values of the eigenvalues of \(G\) distinct from \(d\). Then the toughness \(t\) of \(G\) satisfies \(t> d/\lambda- 2\).

Development of SiC Nanocomposites Using Direct Ink Writing Process

open access: yesAdvanced Engineering Materials, EarlyView.
Herein, feedstock inks containing polycarbosilane and various concentrations of SiC nanoparticles (SiCnp) are investigated for fabricating ceramic matrix composites using a DIW 3D printing process. Characterization results from physical measurement, microstructure analysis, and thermal and flexural testing suggested that high‐performance CMC samples ...
