Abstract: 
The microsegregation pattern of aluminium and silicon in the nodular cast irons has been investigated Microscopic analysis by EDX and EPMA indicates that there is inhomogeneity in the matrix of the as-cast experimental irons. Al is enriched at areas close to the graphite nodules, whereas the concentration of silicon is higher in the intercellular regions. Furthermore, the results obtained on the austenitised Al-alloyed ductile irons at 920 C at different holding times indicate that austenitising reduces the inhomogeneity of the as-cast microstructure and that after sufficient holding time, the matrix of Alalloyed ductile irons containing different Al concentrations can be virtually segregation free.
