“…In recent years, a number of investigations on the effects of hydrogen in iron, steel and other metals have been carried out [1][2][3][4][5][6]. Since hydrogen embrittlement is one of the serious problems related to steel when it is exposed to various environmental conditions, there is great interest in the mechanical and kinetic behaviour of the hydrogen-iron binary system.…”

The energetics of hydrogen atoms interacting with a cluster model of -Fe, having a stacking fault zone, have been investigated. The system energy is calculated using the atom superposition and electron delocalization molecular orbital (ASED-MO) method. By modifying the geometrical positions of the impurity within the cluster we found that H occupies nearly octahedral sites on a stacking fault plane. A second H residing near the former and the possible formation of H-H pairing is also addressed. The relative stability of H-H pairs in the iron matrix is compared with that of the molecule, in the vacuum.
