In the present study, effect of austenitizing time at
intercritical austenitizing temperatures was investigated on the
microstructural features of ductile cast iron. For this aim,
unalloyed ductile cast iron samples intercritically austenitized at
790 and 800 ° C for 1, 5, 15, 30, 60 and 120 min. The samples
were water quenched following intercritical austenitizing. Ferrite
+ martensite dual phase matrix structures have been observed in
intercritically austenitized and quenched samples. Martensite
volume fraction was increased with increasing austenitizing time.
The martensite volume fraction was significantly increased up to
30 min and no remarkable increment in martensite volume
fraction after 30 min. The martensite volume fraction can be
controlled both intercritical austenitizing time and temperatures.
