An Overview of the Mechanical Properties of FeAl

Abstract

AbstractThis paper presents an overview of the mechanical properties of the iron aluminide FeAl. Both the strength and ductility depend on a variety of parameters, including vacancy concentration, the environment (principally water vapor), alloy stoichiometry, temperature and grain size. The effects of alloying elements, particularly boron, are also briefly discussed. The review emphasizes how much of our current understanding of the strength and ductility of iron aluminides emanated from the discovery of the importance of both water vapor and thermal vacancies on these properties.
