Nickel-Based Superalloys

2016
Nickel-based superalloys are an exceptional class of structural materials for high temperature applications, particularly in the challenging environment of the turbine sections of aircraft engines. Continued improvements in the properties of these materials have been possible through close control of chemistry and microstructure as well as the ...

Hydrogen embrittlement in Nickel-base superalloys Nickel-based superalloys in the petrochemical industry

Advances in Engineering Technology Research, 2023
Due to the excellent properties of nickel-based superalloys, it is often widely used in aircraft engines, petroleum, chemical and nuclear energy. However, the use of nickel-based superalloys in petrochemical industry is usually accompanied by hydrogen embrittlement, which will lead to a decrease in its mechanical properties.

Rapidly solidified nickel-base superalloys

Journal of Materials Science, 1980
The structures of rapidly solidified APK1, In 100 and low-carbon In 792 are described and compared with that of Nimonic 80A. Under identical processing conditions, cellular, dendritic and homogeneous equiaxed structures can be obtained. This is not due to either the influence of cooling conditions or to any single alloying addition, but depends on the ...

Nickel-Based Superalloys

2018
The reason that vast numbers of people fly these days is because flying is relatively inexpensive. Once the aircraft has been paid for, the big operating cost for airlines is the cost of the fuel, and fuel efficiency has increased by over 45% since the 1940s.
