The primary objective of this study was to correlate AE signals with the stress-strain curve of the deformation prcess. A combination of uniaxial tensile testing and in-situ acoustic emission measurements was employed to capture real-time AE and simultaneous stress-strain data. Optical microscopy and scanning electron microscopy (SEM) were used to get additional microstructural informations and determine the chemical composition. This research offers a thorough exploration of the acoustic emission phenomena in TWIP steels, highlighting how AE can serve as an effective tool for real-time monitoring of material behavior during mechanical testing.59enacoustic emissiontwip steelstensile testPhysicsHozzáférhető a 2022 decemberi felsőoktatási törvénymódosítás értelmében.
