A Review on Superalloys and IN718 Nickel-Based INCONEL Superalloy

In this paper superalloys, their processing and application areas have been researched. The superalloys are widely used in the industrial production elds such as aircraft, nucleer, space industry and so on due to superior properties at high temperature and resistance to metallurgical and structural variations. The most important groups of the superalloys is Ni, Fe and Co-based superalloys. Also processing of the superalloys are investigated and another goal of the present paper is to investigate microstructure and mechanical properties of IN718 subjected to strength ening heat treatment.
