Characterizing Fracture Development in Ti-Alloy with I-Type Cracks Using Acoustic Emission and Thermal Infrared Imaging

Abstract:

This paper discusses the plastic deformation and fracture development of Ti-alloy under uniaxial tension. The energy dissipation and transfer characteristics in the plastic deformation and fracture processes were analyzed using acoustic emission (AE), thermal infrared (TIR) imaging, and thermocouples. Uniaxial tension tests were carried out, during which TIR images were obtained and the AE energy was observed. The mechanical characteristics of Ti-alloy with I-type cracks were analyzed based on the TIR images, AE energy, and temperature. The plastic work of the Ti-alloy specimen was found to dissipate as thermal energy rather than AE energy. Moreover, the TIR images were correlated well with the AE energy observed during the plastic deformation and fracture processes of the material.
