Isothermed Ductile Iron (IDI) is produced by heat-treating an unalloyed ductile iron, casted with aspecial preconditioning of the metal bath. The matrix structure of the grade IDI consists predominantly of ferrite and pearlite, distributeddifferently from the usual shapes of the as cast grades. The new matrix is called perferritic andgives to the new material unique mechanical properties. The grade IDI is subject of a patent application by Zanardi Fonderie SpA.
Material notes
IDI
ADIAustempered Ductile Iron (ADI) is produced by heat-treating an alloyed ductile iron, casted with aspecial preconditioning of the metal bath.
The matrix structure consists predominantly of ferrite and austenite, depending on the grade. Thenew matrix is called ausferritic and gives to the new material unique mechanical properties.
