Acoustic emission investigation of 15Х2МФА and 15Х2МФА-А steel specimens for different degree of its degradation were performed. Typical peculiarities of change of acoustic emission signal parameters during quasi-static propagation of crack were found. Found parameters could be used in formation of...
