Abstract This article discusses the composition, structure, and properties of iron-nickel-, nickel-, and cobalt-base superalloys and the effect of major alloying and trace elements. It describes the primary and secondary roles of each alloying element, the amounts typically used, and the corresponding effect on properties and ...

<div class="htmlview paragraph">Unidirectionally solidified eutectics offer a favorable approach for producing high strength multiphase materials where one phase serves as the matrix and the other phase or phases serve as the reinforcement. In addition to high strengths, these composite materials generally exhibit excellent microstructural ...

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.
