Resumen:
A study of H absorption near a Fe vacancy in a B2 FeAl alloy is performed using density functional calculations. The H locates in an octahedral site (Al capped) where one of the Fe atoms in its base is replaced by a vacancy.  The computed Fe–H equilibrium distance is 2.065Å and the H becomes negatively charged.  The overlap population analysis reveals metal–metal bond breaking being the intermetallic bond the more affected.
