Non-destructive techniques are used widely in the metal industry in order to control the
quality of materials. Eddy current testing is one of the most extensively used non-destructive …

Collecting state-of-the-art knowledge from information scattered throughout the literature,
this handbook describes magnetic materials and sensors, the testing of magnetic materials …

Pulsed eddy current (PEC) testing was originally reported to sort out heat-treated bearing
rings noncontactly and nondestructively in terms of hardness, which is expected to solve the …

The detection sensitivity and lift-off impaction of the eddy current sensing are the challenges
in the field of electromagnetic nondestructive testing. Higher detection sensitivity, larger lift …

In the field of pulsed eddy current (PEC) testing, the lift-off effect can mix up the signal
features used for surface hardness classification. In order to improve the accuracy of …

This book edited by Tribikram Kundu is an expanded and updated version of Ultrasonic
Nondestructive Evaluation: Engineering and Biological Material Characterization (CRC …

Cryogenic turning can be used to produce deformation-induced martensite in metastable
austenitic steels. Martensite exhibits a higher hardness than austenite and increases the …

Bearings are central components of rotating machinery. Original equipment manufacturers
must utilize high-quality bearings for desirable performances and safety of the equipment …

Industrially unfavorable process of steel surface decarburization was induced by annealing
in air. Two methods of after-anneal surface treatment were used: an acid pickling and a sand …

A multifrequency electromagnetic sensor was used to measure decarburization in steel.
Decarburization samples were generated by heat treating Fe–0.8 wt.% C steel rods for …
