The need for high temperature materials is encountered in a wide variety of modem industries such as in metallurgical, chemical, petrochemical, glass manufacture, heat treatment, waste incinerators, heat recovery, advanced energy conversion systems and others. Depending on the condition of chemical make-up and temperatures, a variety of aggressive corrosive environments are produced, which could be either sulfidizing, carburizing, halogenizing, nitriding, reducing and oxidizing in nature or a combination thereof All high temperature alloys have certain limitations and the optimum choice is often a compromise between the mechanical property requirement constraints at maximum temperature of operation and environmental degradation constraints imposed due to the corrosive species present. This paper addresses the various deterioration mechanisms in metallic alloys system due to the above modes of attack and the role of various alloying elements in minimizing the environmental degradation. Some laboratory and field data on two new nickel base alloys are also presented.
