摘要：A non-destructive testing (NDT) method for evaluating mechanical performance has been studied based on the analysis of eddy current signals. Low-alloy steel samples were tested under conditions of tension with the aim of quantifying hydrogen embrittlement (HE). The mechanical responses of samples were investigated after electrochemical hydrogen charging. Eddy current signals were gathered to evaluate the hydrogen embrittlement state using a differential probe. Numerical analysis of hydrogen concentration distribution in material was performed to investigate the response mechanism of the signal. The effect that hydrogen has on the mechanical performance of low-alloy steel has been discussed. The experimental results show that the eddy current signal has a good correlation with the hydrogen-induced plasticity loss index.
