Eddy current detection of changes in stainless steel after cold reductions

Cold rolling of austenitic stainless steel results in increase of residual stresses, hardness, and tensile strength and dislocation density. We have studied the response of eddy current impedance to austenitic change, hardness and its lift off phase in stainless steels during cold reductions. A series of samples of austenitic stainless steel alloys were cold rolled and found that only percentag...

Eddy Current System for Material Inspection and Flaw Visualization

Eddy current methods have been successfully used in a variety of non-destructive evaluation applications including detection of cracks, measurements of material thickness, determining metal thinning due to corrosion, measurements of coating thickness, determining electrical conductivity, identification of materials, and detection of corrosion in heat exchanger tubes. This paper describes the de...

Analysis of Fatigue Crack Paths in Cold Drawn Pearlitic Steel

In this paper, a fracto-metallographic analysis was performed on the cracked specimens of cold drawn pearlitic steel subjected to fatigue tests. Fatigue cracks are transcollonial and exhibit a preference for fracturing pearlitic lamellae, with non-uniform crack opening displacement values, micro-discontinuities, branchings, bifurcations and frequent local deflections that create microstructural...

Eddy-current probe impedance due to a volumetric flaw

Eddy current induced in a metal by a coil carrying an alternating current may be perturbed by the presence of any macroscopic defects in the material, such as cracks, surface indentations, or inclusions. In eddy-current nondestructive evaluation, defects are commonly sensed by a change of the coil impedance resulting from perturbations in the electromagnetic field. This paper describes theoreti...

Flaw Detection and Characterization of Pressure Tubes from CANDU PHWR using Eddy Current Methods

This paper presents a new type of eddy current transducer, send-receiver type, using the rotating magnetic field method. The forward problem was solved, the experimental results obtained for detection of different types of degradation have proved the capability to emphasize blisters, and garter springs location and tilt as well as hydrogen content. INTRODUCTION The nondestructive testing of met...
