A comprehensive study was made of the mechanism and kinetics of corrosion of Al--Fe --Ni alloys in hightemperature water and steam. Three corrosion mechanisms were observed: production of a uniform film, production of a disordered film, and intergranular corrosion. It appeared that the basic corrosion process was identical in all experimental conditions. The corrosion of welded alloys was especially considered. Metallurgical processes and mechanisms influencing the behavior of aluminum alloys with respect to corrosion by high- temperature water were investigated. Classical metallurgical methods and powder metallurgical methods were considered. The results of this study indicate the equal importance of chemical, electrochemical, and metallurgical factors and creep characteristics in the preparation of corrosion-resistent alloys. (J.S.R.)
