Introduction
Super alloys are alloys, which are capable of functioning at high temperature and mechanical stress, and also where high surface stability is needed. They can be strengthened by solid-solution hardening, precipitation hardening, and work hardening. They have good creep and oxidation resistance. They are divided into three types such as cobalt-based, nickel-based, and iron-based alloys.
