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.

The overview of the formation mechanisms of topologically close-packed phases in Ni-based single crystal superalloys

Materials & Design
The nucleation and growth of topologically close-packed (TCP) phases in Ni-based single crystal superalloys (SCs) are controlled by composition, temperature, time, interface structure and stress.
