چکیده

Vector hysteresis models are applied to an eddy-current analysis. The vector hysteresis models are composed by play hysterons and stop hysterons. The eddy-current analysis shows that both play and stop hysteron models can effectively describe isotropic vector hysteretic behavior. The stop hysteron model is more efficient in analyzes using the magnetic vector potential than the play model because the stop model can give the magnetic field from the magnetic flux density without an iteration process.

Design of Nondestructive System for Hardness of Carbonitrided Steel Parts ‎Using Eddy Current Testing Method: Case study on the Tappet Parts

In this paper, a non-destructive eddy current test system was designed to evaluate the surface hardness of the carbonitrided steel parts. For this purpose, various samples of the tappet were used after the surface hardening and grinding operations as control samples and, if necessary, were subjected to destructive and non-destructive tests. Microstructural studies were performed with a microsco...

Applications of Impedance Plane and Magnetic Differential Permeability in Microstructural Characterization of AISI D2 Tool Steel

Two nondestructive electromagnetic/magnetic techniques including hysteresis loop and eddy current methodologies have been used to characterize microstructural changes of AISI D2 cold work tool steel as a result of quench and tempering treatments. To measure the fraction retained austenite in quenched microstructure, six specimens were austenitized in the range  of 1000-1130 °C. Samples austenit...
