RISNONDESTRUCTIVE EVALUATION OF MECHANICAL PROPERTIES OF DUCTILE CAST IRON PARTS USING EDDY CURRENT SIGNALS
The present research investigates improvement of Eddy Current (EC) technique as a
nondestructive method for measurement of ductile cast iron microstructural and mechanical
characteristics. Six samples of heat ...
Nondestructive characterization of induction hardened cast iron parts
Surface hardening is commonly applied to improve wear and fatigue
properties of industrial parts. From practical point of view, determining the depth of
hardened layer is important in quality control process ...
Effect of sample initial magnetic field on the metal magnetic memory NDT result
One of the major concerns regarding the use of Metal Magnetic Memory (MMM) technique is the complexity of residual magnetization effect on output signals. The present study investigates the influence of residual magnetic ...
Magnetic NDT Technology for characterization of decarburizing depth
From practical point of view, determining the decarburizing depth is important in quality control of steel parts as it has undesirable effects on the mechanical properties such as hardness, wear and fatigue resistance. ...
Magnetic nondestructive technology for detection of tempered martensite embrittlement
A nondestructive eddy current technique is used to evaluate tempered martensite embrittlement in
4340 AISI steels after quench and tempering in the range 240–550 1C. A relation between the responses
of the ...
