    Acoustic Emission During Structural Transformation in TWIP Steels
    Guliyeva, Mehin; Dároczi, Lajos; DE--Természettudományi és Technológiai Kar--Fizikai Intézet
    This thesis investigates the acoustic emission (AE) behavior during deformation of FeMn(Cr) steel. 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.
