Synchronously enhanced printability and properties of additively manufactured nickel-based superalloys via alloying minor Sc

Journal of Materials Research and Technology
As major forming elements of γ′ strengthening phase, Al and Ti are critical for achieving superior properties of Ni-based superalloy. However, Al + Ti over 6 wt% leads to poor printability and cracking during additive manufacturing.

Where Can Aluminum Go When Batteries Die?

Advanced Science, Volume 13, Issue 7, 3 February 2026.
Battery‐derived aluminum is transformed from contaminated waste into an alloying resource for high‐performance Fe‐based alloys. Through controlled Al content and processing, dual‐phase austenite/ferrite microstructures with TRIP‐like behavior are achieved.

The dynamic recrystallization of the Ni-based superalloy under the supergravity stress and high temperature

Materials Research Letters
The occurrence of recrystallization will greatly decrease the service life of superalloy blades. The dynamic recrystallization of a Ni-based single crystal superalloy under supergravity stress and high temperature was studied. When tested at 950 °C, only

A Novel Approach for ∆K Estimation in the Fatigue Threshold Region Based on ΔKth and Kmax,th

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 2, Page 653-662, February 2026.
ABSTRACT A novel procedure, proposed by Kujawski and Vasudevan 1, has been evaluated as an alternative to the ASTM E647 standard for determining the ∆Kth and Kmax,th thresholds. This method relies solely on the actual propagation of cracks, which occurs only when both thresholds are satisfied simultaneously. For long cracks, a more efficient estimation

Soldering Si3N4 to Invar42 by a localized heating process

International Journal of Applied Ceramic Technology, Volume 23, Issue 1, February 2026.
Abstract This study investigates the soldering process for joining silicon nitride (Si3N4), a commonly used ceramic, to Invar42, a low thermal expansion alloy. The focus lies on analyzing interfacial reactions and evaluating the bonding performance of the Si3N4—Invar42 joint.

Synthesis and thermal properties of dense Si─Al─C─N‐based polymer‐derived ceramics

International Journal of Applied Ceramic Technology, Volume 23, Issue 1, February 2026.
Abstract In the present study, aluminum‐modified preceramic silicon polymers were synthesized via chemical modification of a commercially available organopolysilazane using an aluminum amido complex. The incorporation of aluminum into the polymer structure and its effect on ceramization behavior and processability as well as the thermal and mechanical ...
