Nondestructive testing (NDT) techniques are used to evaluate the material degradation of
ferromagnetic materials, for example, in sensitive environments, such as thermal power …

The magnetization processes have been used for years to observe mechanical or
microstructural properties in ferromagnetic steel. The usual techniques rely on standard …

The aim of this paper is to assess the stress concentration zone (SCZ) of a circular smooth
specimen at an early stage. Following the detection of the stress concentration zone, the …

The use of specimen loss factor as fatigue damage indicator of Hastelloy-X substrates with
different surface treatments was investigated together with other fatigue damage indicators …

The magnetic frequency mixing method was investigated for fatigue damage evaluation of
medium carbon steel. Two types of magnetic signal, the magnetic flux density and the …

Fatigue damage was investigated by the method of magnetic adaptive testing (MAT), which
is based on the systematic measurement and evaluation of minor magnetic hysteresis loops …

Praca dotyczy wykorzystania metody prądów wirowych oraz innych metod nieniszczących
do identyfikacji lokalnych zmian w strukturze materiału związanych z rozwojem uszkodzenia …

This work focuses on the investigation to evaluate a material parameter, namely a
contraction value ψ, at failure in estimating the fatigue life of ferromagnetic steel based on …

With respect to harmonic generation measurements in isotropic materials, the amplitude of
the third-harmonic wave generally depends on both β 2 (the square of the second-order …

We applied eddy current transducer (ECT) to examine the electric steel parameters. The
research topic is considered relevant due to the need for evaluation and forecasting of safe …
