Orientation relationship of eutectoid FeAl and FeAl₂.

ABSTRACT: Fe-Al alloys in the aluminium range of 55-65 at.% exhibit a lamellar microstructure of B2-ordered FeAl and triclinic FeAl₂, which is caused by a eutectoid decomposition of the high-temperature Fe₅Al₈ phase, the so-called ∊ phase. The orientation relationship of FeAl and FeAl₂ has previously been studied by Bastin et al. [J. Cryst. Growth (1978 ▸), 43, 745] and Hirata et al. [Philos. Mag. Lett. (2008 ▸), 88, 491]. Since both results are based on different crystallographic data regarding FeAl₂, the data are re-evaluated with respect to a recent re-determination of the FeAl₂ phase provided by Chumak et al. [Acta Cryst. (2010 ▸), C66, i87]. It is found that both orie
