... that has become widely used because of its attractive mechanical properties for a relatively cheap cast iron. It is widely referred to as austempered ductile iron (ADI). As discussed in Chapter 12, “Quenching,” the austempering produces a bainite structure that, particularly at the high carbon levels...

... the centuries. Gray cast iron is the most basic and commonly used grade. Other popular types are ductile iron, austempered ductile iron (ADI), and white iron. Gray cast iron is the weakest and simplest grade, and it is widely used for mechanical components, such as gears and cams, and large buried pipes...

...-bainite structures in a 0.9% C steel Perhaps the most widespread use of austempering is in the foundry industry, where ductile cast iron is processed in such a way as to produce austempered ductile iron (ADI). The performance of ADI gears rivals that of conventional carburized gears, and production...
