Superalloys are unique high-temperature materials used in gas turbine engines, which display excellent resistance to mechanical and chemical degradation. This book presents the underlying metallurgical principles which have guided their development and practical aspects of component design and fabrication from an engineering standpoint.

Metallurgical and Materials Transactions A, 1996
The phenomenon of rafting in superalloys is described, with particular reference to modern superalloys with a high volume fraction of the particulate γ’ phase. It is shown that in the elastic regime, the thermodynamic driving force for rafting is proportional to the applied stress, to the difference between the lattice parameters of the γ matrix and ...

Physica Status Solidi (a), 1992
The mechanical properties of Laves phases, and of alloys containing Laves phases, are reviewed with an eye to their potential as high-temperature structural materials. Several two-phase alloys show promising combinations of high-temperature strength and low-temperature toughness, and extensive room-temperature deformability of the cubic Laves phase by ...

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.

Understanding Superalloy Metallurgy
2002Abstract This chapter describes the metallurgy of superalloys and the extent to which it can be controlled. It discusses the alloying elements, crystal structures, and processing sequences associated with more than a dozen phases that largely determine the characteristics of superalloys, including their properties, behaviors, and ...
