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.

An automated segmentation for nickel-based superalloy
2008 15th IEEE International Conference on Image Processing, 2008We investigate the automated segmentation of microstructures of a nickel-based superalloy using digital microscopy data. We study the combination of a region merging segmentation method called the stabilized inverse diffusion equation (SIDE), and a stochastic segmentation method, the expectation-maximization/maximization of the posterior marginals (EM ...

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.

The recrystallization of nickel-base superalloys
Journal of Materials Science, 1981The effects of recrystallization on the γ′ distribution in four nickel-base superalloys of varying γ′ volume fraction (Nimonics PE16, 80A and 115, and Udimet 720) have been studied by transmission electron microscopy. These effects are explained in terms of high solubility and diffusivity in the recrystallization interface, and it is suggested that ...

The so-called nickel-base superalloys or high-strength high-temperature alloys are, in general, modifications of the corrosion- and heat-resisting alloys of the types discussed in Chapters 3 and 4. Their improved strength and creep resistance at elevated temperatures have been developed by including elements which will produce a stable hard phase or ...

Defects in Nickel-Base Superalloys
JOM, 1987In the sixty years since age-hard-enable, nickel-base superalloys were first identified, the compositional and microstructural features of these high-performance metals have changed markedly—from the early Nimonic (INCO trade name) 80A (a wrought alloy of essentially four elements) to today’s family of wrought from ingot, powder metal, cast and ...
