چکیده
The presence of well distributed graphite in the matrix, and a relatively high volume fraction of retained austenite, are responsible for the good mechanical properties of the austempered ductile irons including excellent wear resistance. It is now well known that the notable properties of ADI directly depend on the volume fraction of retained austenite in the matrix. Consequently, the influence of the aluminium on the detailed microstructure of heat treated irons are examined.
