<p style="text-align: justify;">Austempered Ductile Iron is a class of ductile iron subjected to a specific heat treatment process (austenitization and austempering). The heat treatment gives to that type of Ductile Iron an excellent mechanical properties and an especially good strength-to-weight ratio. However, designers in most cases are unfamiliar with this material that can compete<br />favorably with other type of metallic materials (steel, aluminum, etc). The high tensile strength of ADI is the result of its unique ausferrite microstructure. In this paper, an example of Ductile iron sample production is presented.</p>
