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 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.

Superplasticity of Nickel-based Superalloys
1992Nickel-based alloys are one of the most extensively used groups of heat resistent materials (superalloys) and are frequently found in engines operating at elevated temperatures up to 0.8 T m . The practical significance of nickel-based alloys motivated intense studies on their structure and properties [8.1, 2].

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 ...

NICKEL-BASE SUPERALLOY OXIDATION
1967Abstract : A program to determine the phenomenological oxidation behavior of five commercial nickel-base alloys (IN-100, SM-200, Inco 713C, Rene 41, and U- 700) and one experimental alloy (Rene Y) is described to assure the intelligent application of these alloys and aid in the development of alloys with improved surface stability.
