Fabrication of Sm:LuAG transparent ceramics with different doping concentrations for cladding from co-precipitated nano-powders

Journal of Advanced Ceramics
For high-repetition-rate nanosecond high-power solid-state lasers, it is essential to choose gain media with moderate saturation flux. Among these materials, Nd:Lu3Al5O12 (LuAG) transparent ceramics have shown significant potential.

Revisiting Stability Criteria in Ball‐Milled High‐Entropy Alloys: Do Hume–Rothery and Thermodynamic Rules Equally Apply?

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

Li2CO3-affiliative mechanism for air-accessible interface engineering of garnet electrolyte via facile liquid metal painting

Nature Communications, 2020
At Li-garnet interface, the poor interfacial wettability due to Li2CO3 passivation causes large resistance and unstable contact. Here the authors propose a Li2CO3-affiliative mechanism for air-accessible interface engineering of garnet electrolyte with ...

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

Advanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Ceramic Powders for Advanced Ceramics: What are Ideal Ceramic Powders for Advanced Ceramics?

Transactions of the Materials Research Society of Japan, 2010
One of the most important factors for advanced ceramic preparation is the nature of powders. This article is a review and overview of powder preparation and properties and explains ideal powders for advanced ceramics. In addition, hydrothermal powders that are close to ideal powders are described along with hydrothermal processing.

Experimental Evaluation of 100Cr6 Steel Microindented Surfaces Under Lubricated Nonconformal Point Contacts

Advanced Engineering Materials, EarlyView.
The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

Stability of tricalcium phosphate polymorphs in the Ca3(PO4)2–Zn3(PO4)2–Mg3(PO4)2 system and solid-state compatibilities of CaO–P2O5–MgO–ZnO system at 900 °C

Boletín de la Sociedad Española de Cerámica y Vidrio
Stability and microstructure of tricalcium phosphate polymorphs (TCP) in the Ca3(PO4)2–Zn3(PO4)2·Mg3(PO4)2 phase equilibria diagram from experimental studies between 1200 °C and 1400 °C have been determined.

Modulation of the morphotropic phase boundary for high-performance ductile thermoelectric materials

Nature Communications, 2023
The flexible thermoelectric technique, which can convert heat from the human body to electricity via the Seebeck effect, is expected to provide a peerless solution for the power supply of wearables.

Laser Powder Bed Fusion of Alumina: Effects of Scanning Strategies on External and Internal Defects

Advanced Engineering Materials, EarlyView.
This study investigates how scanning strategies affect pure alumina in laser powder bed fusion. Linear 45° scanning yields uniform surfaces but high porosity, while the island‐concentric strategy provides higher density with through‐holes favorable for infiltration. Findings highlight pathways toward optimizing defect‐free alumina parts.

Effect of Y substitution on the microstructure, magneto-optical, and thermal properties of (Tb1−xYx)3Al5O12 transparent ceramics

Journal of Advanced Ceramics
Faraday isolators can prevent the front-end system from disturbance and damage caused by a back-reflected beam, so they are important elements in laser systems.
