Introduction
Super alloys are also referred to as high performance alloys. They have good creep and oxidation resistance, and are divided into three groups such as cobalt-based, nickel-based, and iron-based alloys. They have an ability to function at very high temperatures and in extreme mechanical stress conditions, and also where high surface stability is required. They can be formed in different shapes, and contain a number of elements in a variety of combinations to obtain the desired result. They are subjected to solid-solution hardening, work hardening, and precipitation hardening in order to increase their strength.
