Acoustic emission investigation of crack propagation in Cr-Mo-V steels of different degradation degrees
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...

| Summary: | 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 new instrumentality for acoustic emission monitoring of reactor vessels of nuclear power plant |
