Abstract

The origin of acoustic emission (AE) in 7075 aluminium alloy was investigated in tension and compression tests. It is suggested that the first peak associated with the root-mean-square (rms) AE plot against time (or strain) is due to the unpinning of dislocation segments from solute atom clusters and is not due to the fracture of particles. Alteration in the value of the AE first peak and also in electrical resistivity values due to heat treatment of this alloy support the proposed origin of the AE first peak near yield.
