ARTICLE Description of austempering and its advantages
Austempering is a process of applying heat treatment on ferrous metals, like steel and iron. This procedure is basically done for improving mechanical properties of metal. The procedure begins with heating the metal till its austenitic state and then rapidly cooling it; along with maintain a high temperature for prevention of formation of martensite for an enhanced duration. By the use of this process, metals become tougher, strong and resists to wear and tear.

The main aim of austempering is to provide strength driven materials in various machine parts. The concept of austempering is different from traditional form of heat treating, in which there is quick quenching of austenite in oil or fluid at room temperature. It will form martensite, which is hard, but on the same time, it is highly brittle and needs tempering for becoming ductile. The outcome of austempering is dependent on the material used for the same. Bainite is the name given to austempered steel and it is relatively more ductile than martensite. The final product doesn t require any tempering and is tough, sturdy and adds wear resistance. On the other hand, austempered ductile iron results in production of ausferrite, which has greater strength. Austempered ductile iron (ADI) is also used in manufacturing of many machine parts.
