چکیده مقاله :
This study aimed to compared mechanical properties and failure mechanisms in ferrite and martensite samples, using Acoustic Emission (AE) Non-Destructive Testing (NDT). The purpose of this study is to identify the phases of ferrite and martensite by analyzing the parameters of AE. Tensile testing was performed on the samples and AE signals were recorded. The Sentry Function (SF) and Fast Fourier Transform (FFT) were used to analyze signals. The results of the martensite sample show that the SF is almost constant at the beginning. This indicates a relative balance between the AE energy and the strain energy. Then the SF took a downward state, which demonstrates a greater ratio of acoustic energy to strain energy. Frequency distribution, one of the best parameters to identify the failure mechanisms in materials for the ferrite sample, is significantly in the range of 175 kHz, while for the martensite sample, this range is between 520 and 700 kHz.
