چکیده:

Considering the importance of austenization in preparing steel, it is crucial to have a good understanding of the effects of temperature on this process. In this project, we studied these effects on an aluminum-containing ductile iron sample. We exposed many of these samples for 30 minutes to 890, 920 and 950 Celsius degrees and immediately quenched them in cold water. Micro-structural studies and XRD tests show that samples prepared in 950 degrees have a better micro-structure and hardness. In addition, we found that heat treatment of the as-cast samples containing Fe3Si in matrix microstructure causes the disappearance of this phase
