The Two-Frequency Analysis оf Acoustic Emission Signals аt Deformation аnd Destruction оf Aluminium Alloys

Investigation of applicability of the spectral analysis of acoustic emission signals at plastic deformation and destruction of aluminium alloys was conducted. Updating of a method of the detecting was offered, allowed to carry out the two-frequency analysis of signals in real time and device of measurements in which it is realized was described. Results of the acoustic emission testing received at deformation of alloy D16 were resulted. Correlation between stages of plastic deformation and the factor characterizing the contribution of various frequencies in power of acoustic emission signal was found.

Keywords: emission, plastic deformation, fracture.
