Interrelations between phase diagrams and hydriding properties for alloys based on the intermetallic compound FeTi+
Hydriding alloys based on the intermetallic compound FeTi have potential for the safe and convenient storage of hydrogen, both for mobile and stationary applications. In spite of its simple formula, the hydriding behavior of FeTi is quite complex and a strong function of alloy microstructure. The alloy microstructure, in turn, depends on composition, not only deviations from stoichiometry but also various impurities. In this paper we discuss some of the interrelations among composition, microstructure, and hydriding behavior that can be related to phase diagram information. In particular, we discuss the Fe--Ti, Fe--Ti--O, and Fe--Ti--Mn phase diagrams and their relationships to hydriding properties. The use of hydriding data to infer metal-hydrogen phase diagrams is also briefly discussed.
