Journal: Nondestructive Testing and Evaluation Publication date: 29 Apr 2014 Abstract: The present paper describes details of the comparison on the capability of eddy current (EC) and magnetic Barkhausen noise (MBN) techniques in the assessment of different microstructures in mild steel.
Journal: Metal Science and Heat Treatment Publication date: 30 November 2013 Abstract: Cast iron with globular graphite is studied after surface induction hardening. Hardness profiles of iron bars are plotted for determining the thickness of the hardened layer. Relations between the thickness of the hardened layer and the output voltage are obtained by the method […]
Journal: Materials Science and Technology Publication date: 18 Nov 2013 Abstract: Machinability of grey cast iron parts can greatly suffer from the formation of carbide at the surface, resulting in a decrease in cutting tool life and higher production costs. Therefore, detection of the hardened layer and its hardness are the key factors in quality […]
Journal: Journal of Materials Engineering and Performance Publication date: 15 September 2012 Abstract: Inspection and quality control of induction hardened parts require a good understanding of the depth of the hardened layer. Traditional destructive methods to determine the case depth are considered to be costly and time-consuming. The eddy current (EC) technique is sensitive to […]
