网页2020年5月1日 · Composition greatly determines the development of microstructures in superalloys. With the change of alloying contents, microstructural characteristics such as the size and volume fraction of γ′ phase, the form of γ/γ′ interface and the distribution of precipitated phase are consequently changed.
Superalloys - an overview | ScienceDirect Topics
网页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.
