چکیده مقاله:
Austempered Ductile Irons (ADI) are materials which have attractive properties such as ductility, high strength, hardness and good wear resistance. These properties can be achieved by proper chemical composition, heat treatment and adequate microstructure. The main barrier in progress application of ADI, is low machinability. In this paper, an investigation has been conducted on ADI Alloys with different heat Traetment times and temperatures and measuring of hardness as a criteria for machinability. It was shown that by increasing in Austenizing and austempering temperatures, the hardness decrease, which it is benefit to increase machinability. Based on these results an optimal processing window has been established.
