Abstract

<p>Austempered ductile iron, commonly known as ADI, has already gained some renown among producers and users of castings made from this material. Though famous nowadays, its properties are being improved all the time and studies are continued to better know the mechanisms that govern obtaining the properties so unusual for a material like cast iron. From the research carried out by the author of this publication it follows that at least some of the properties result from the phenomenon that is called martensitic transformation and that accompanies the formation of ADI at different stages of its manufacture and during the additional technological operations. In ADI microstructure, martensite is always the product of austenite transformation, and for this reason mainly an attempt has been made in this paper to describe this phase in more detail as well as various consequences of its presence in cast iron under different conditions.</p>
