Introduction
Super alloys are also referred to as high performance alloys. They have good creep and oxidation resistance, and are utilized where high surface stability is required. They also have an ability to function under high temperatures and mechanical stress. They can be strengthened by solid-solution hardening, work hardening, and precipitation hardening. They are divided into three groups such as iron-based, nickel-based, and cobalt-based alloys.
