Application of the frequency analysis of acoustic emission in the study of the metal alloy solidification
A frequency analysis of the acoustic emission signals was
applied for the investigation of the solidification of a Pb-Sb alloy. Spectra of
continuous emission and short-time acoustic emission impulses were investigated.
It has been stated that, together with structural changes of the Pb-Sb alloy,
significant changes occur in the spectra of the acoustic emission impulses
generated in different phases of solidification. Less significant changes were
observed in continuous acoustic emission spectra.
