Abstract
The acoustic emission (AE) method has been applied for the first time in the investigations of the strain localization phenomena (shear banding) occurring in copper and silver as well as in copper-aluminium alloy single crystals under channel-die compression in plane state of strain at liquid nitrogen temperature (77 K). It has been found that the rate of AE events is correlated with the transition from the twinning mode to the shear band mode of the deformation process. Moreover, it has been observed that pronounced correlations between the AE behaviour and the nearly periodic drops of the external force are related with the beginning of shear bands formation. The presented results are discussed in terms of both dislocation acceleration and annihilation processes accompanied by the operation of the Frank-Read sources as well as accompanied by the escape of dislocations from the crystal to a free surface, including the partial dislocations engaged during the operation of the pole mechanism of twinning. Moreover, it has been pointed out that the dislocation annihilation and the step formation on a free surface can be also considered in terms of the dynamics of dislocation kinks treated as the solitary wave processes.
