In this study, effect of air cooling from intercritical
austenitizing temperatures on microstructure and hardness in
GGG70 grade ductile cast irons. For this aim, ductile cast iron
specimens air cooled from intercritical austenitizing
temperatures at 780°C, 790°C, 800 °C, 810 °C, 820 °C, and
830 °C for 30 minutes. Experimental results showed that, pearlite
volume fraction and hardness increased with increasing
intercritical austenitizing temperatures. It can be produced
ductile cast irons which has different pearlite volume fraction by
controlling intercritically austenitizating in same chemical
composition GGG70 grade ductile cast iron.
