摘要：

Yield strength detection of ferromagnetic materials in iron and steel industries relied on loss detection, which greatly increased the cost of testing. So, a multi-feature fusion method for yield strength pulsed eddy current testing of ferromagnetic materials was proposed herein. Firstly, the time domain characteristics and frequency domain characteristics of pulsed eddy current response signals were extracted. And then, a neural network model for establishing the yield strength of each signal characteristic and material was established. Finally, the neural network model was used to predict the yield strength of the materials. As a non-destructive testing method, the method may achieve prediction errors less than 5%. © 2019, China Mechanical Engineering Magazine Office. All right reserved.
