Aluminum Alloy Containing Iron and Nickel. Influence of Structure and Composition on the Corrosion Behavior in High Temperature Water; ALLIAGES D'ALUMINIUM CONTENANT DU FER ET DU NICKEL. INFLUENCE DE LA STRUCTURE ET DE LA TENEUR SUR LA RESISTANCE A LA CORROSION PAR L'EAU A HAUTE TEMPERATURE

OSTI ID:4176772
The corrosion structure was determined for a series of Al base alloys having an Fe + Ni content below 3%. The tests ran 5,000 hours in an autoclave at 350 tained C in demineralized water. For contents greater than 0.5% of Fe and Ni, the most important factor is the structure and distribution of intermetallic compounds in the separated phase. The particles should be as fine and as uniformly distributed as possible. The corrosion products formed at the surface subdivide into three distinct layers the total thickness of which tends rapidly toward limit and stabilizes. (tr-auth)
