Heat Capacity Measurements and Thermodynamic Assessment of the Y2O3–Ta2O5 System

Journal of the American Ceramic Society, Volume 109, Issue 2, February 2026.
ABSTRACT Phase equilibria in the Y2O3–Ta2O5 system play an important role in the development of new materials for thermal barrier coating (TBC) applications, with higher thermal stability resulting in more efficient gas turbines with reduced exhaust gas emissions.

Improved high-temperature-strength nickel-base superalloy [PDF]

, 1969
Nickel-base superalloy has a strength of 20,000 psi at 2,200 degrees F, approximately double the strength of the strongest available cast nickel-base alloys. It is not subject to the formation of embrittling phases upon long time exposure at intermediate

High‐Entropy Alloy Design Toward Cobalt Substitution for High Hardness and Low Wear Rate Using X–Cr–Fe–Mn–Ni System

Advanced Engineering Materials, Volume 28, Issue 2, January 21, 2026.
This study explores the replacement of cobalt using the high‐entropy alloy design strategy for wear‐resistant components operating at high temperatures. Starting from the Cantor alloy, cobalt is substituted with Cu, Al, V, or Mo. Metallurgical and tribological analyses reveal that aluminum, vanadium, and molybdenum effectively strengthen the developed ...

Additively Manufacturable High‐Strength Aluminum Alloys with Coarsening‐Resistant Microstructures Achieved via Rapid Solidification

Advanced Materials, Volume 38, Issue 4, 16 January 2026.
Rapid solidification in laser additive manufacturing facilitates the precipitation of metastable phases in aluminum alloys. These metastable phases significantly enhance the strength by forming a high‐volume fraction of precipitates with an order of magnitude reduced sizes and smaller interspacing, effectively impeding dislocation motion. Consequestly,

Spectroscopic Reactor for Operando Investigations Made by Additive Manufacturing for High‐Pressure Catalysis Applications

Chemistry–Methods, Volume 6, Issue 1, January 2026.
A spectroscopic reactor for operando X‐ray studies under high‐pressure conditions is developed and fabricated via additive manufacturing. Its two‐zone design allows independent temperature control and catalyst loading, enabling studies at different conversion levels. A large window permits spatially‐resolved X‐ray analysis.

Effect of a heterogeneous distribution of particles on the formation of banded grain structure in wrought Alloy 718 [PDF]

, 2005
Alloy 718 is known to be sensitive to interdendritic segregation formed during ingot solidification. The occurrence of banded grain structures under heat treating conditions close to 1000 ° C related to interdendritic segregation is often reported.

Oxidation Performance of NiCoCrAlYTa + 7YSZ Coatings With Ta Addition at Different Temperatures

Rare Metals, Volume 45, Issue 1, January 2026.
ABSTRACT This study investigates the morphology and oxidation behavior of thermally grown oxides (TGO) formed at the interface of NiCoCrAlYTa + 7YSZ (7 wt% Y2O3‐stabilized zirconia) coatings deposited by air plasma spray (APS) in air environments at 1050°C, 1100°C, and 1150°C. The enrichment of Ta‐rich oxides beneath the TGO, along with the segregation
