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.

A History of Superalloy Metallurgy for Superalloy Metallurgists

Superalloys 1984 (Fifth International Symposium), 1984
This “history” is an attempt to tell their story. However, it is not intended to be simply a logical recording Iof the events that have transpired to create them, but is intended to be a technically and scientifically useful analysis through chronological treatment, based upon consideration of the development of their significant property factors, the ...

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, 21 January 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 ...

Fiber Reinforced Superalloys [PDF]

, 1989
Improved performance of heat engines is largely dependent upon maximum cycle temperatures. Tungsten fiber reinforced superalloys (TFRS) are the first of a family of high temperature composites that offer the potential for significantly raising hot component operating temperatures and thus leading to improved heat engine performance.
