Superalloy - Wikipedia
A superalloy, or high-performance alloy, is an alloy with the ability to operate at a high fraction of its melting point. [1] . Key characteristics of a superalloy include mechanical strength, thermal creep deformation resistance, surface stability, and corrosion and oxidation resistance.
Superalloys - an overview | ScienceDirect Topics
Superalloys are a group of nickel, iron–nickel and cobalt alloys used in jet engines. These metals have excellent heat resistant properties and retain their stiffness, strength, toughness and dimensional stability at temperatures much higher than the other aerospace structural materials.
What are Superalloys - Definition | Material Properties
Superalloys, or high-performance alloys, are non-ferrous alloys that exhibit outstanding strength and surface stability at high temperatures. Their ability to operate safely at a high fraction of their melting point (up to 85% of their melting points (T m) expressed in degrees Kelvin, 0.85) is their key characteristics.
What Are Superalloys? (Applications, History, and Metallurgy)
2021年5月11日 · Superalloys are metal alloys that can operate at a high fraction of their melting point. Superalloys must have high strength, high melting points, resistance to corrosion or oxidation, and creep resistance.
A superalloy, or high-performance alloy, is an alloy usually based on Group VIII A elements that exhibits excellent long-time strength, creep resistance, corrosion and erosion at temperatures above 1200oF, good surface stability, and corrosion and oxidation resistance.
