Characterization of Hadfield Steels Subjected to Various Heat-Treating Processes by Nondestructive Eddy Current Method

Journal: Russian Journal of Nondestructive Testing Publication date: 23 December 2019 Abstract: A nondestructive eddy current method has been used to characterize microstructural features of Hadfield steels subjected to various conditions of heat treatment. The heat treatment parameters including quenching media (furnace, air, and water) and tempering temperatures (in the range of 200–600°C) were varied […]
