The temperature for the start of martensite formation (MS) for three Al-alloyed ductile irons containing 0.48%Al, 4.88%Al and 6.16%Al were determined by high-speed dilatatometry. Microscopic observation and hardness measurements also were used to indicate the effects of aluminium addition on the martensite transformation during quenching. The examination confirmed that an austenite/martensite transformation occurs for irons containing 4.88%Al and less. The results indicate that martensitic transformation occurs at about 173°C for 0.48%Al and 4.88%Al. Whereas there was no evidence of the martensitic transformation for 6.16% Al .
