Acoustic Emission from the Aluminium Alloy 7050.

Abstract

Studies of the acoustic emission detected during deformation of the commercial aluminum alloy 7050 are described. Tests have been performed on unflawed tensile specimens and notched specimens of the alloy in a variety of heat-treated conditions. Attempts are made to correlate the detected emission with various microstructural features affecting the deformation of the alloy. (Author)
