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 ...

<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 ...
