摘要

Application of the acoustic emission (AE) technique allows investigating collective processes of plastic deformation at different time scales spreading from microseconds up to the duration of the mechanical test. This chapter presents acoustic emission (AE) characteristics of the commercially pure titanium during tensile deformation. The tensile test was carried out with samples of titanium TA2 at 293 K, which was continuously recorded by AE system using two types of AE sensors. The results show that higher AE signals were generated around yielding and fracture of the tensile loading for two types of sensors. The maximum amplitude of AE signals was 80 dB. The frequency distributions of AE signals for resonant sensor and broadband sensor are different. The resonant sensor shows a narrow band (135–160 kHz) of FMAX, while the broadband sensor shows a wide-range FMAX (90-330 kHz). And the FMAX of the broadband sensor with higher frequency (210–330 kHz) occurred around the yield point, and this phenomenon lasted until fracture.
