Investigating the Austempering Parameters of Ductile Iron by Magnetic Barkhausen Noise Technique
The optimum mechanical properties for austempered ductile iron (ADI) can be achieved if the heat treatment is conducted in a restricted time and temperature frame called the processing window. In this study MBN response and variations in microstructure and mechanical properties of ADI have been investigated. In the experiments, unalloyed ductile iron samples have been austenitized, and then, transferred to a salt bath for austempering for various times. It has been observed that there is a very good correlation between MBN response and variations in microstructure and mechanical properties and the processing windows of ADI can be estimated by nondestructive MBN method.
