Abstract
At 850°C the action of the gas phase AlCl3, HCl, H2 on equilibrium with aluminum-iron alloys of various compositions causes the development, on the surface of the iron, of diffusion layers the nature and the composition of which are functions of the ratio Al/Fe of the reacting alloy. With alloys of composition (greater than?) 3, the superficial layer is formed of crystals of the compound Ge2Al5, oriented along the direction /001/; with alloys of composition Al/Fe (less than?) 2, the superficial layer is made of the solid alpha solution which increases epitaxically.
