Abstract
The possibility of fatigue properties regeneration for light-alloy structural
components was investigated by methods of surface plastic deformation (SPD).
Investigations were carried out using aluminium alloy specimens subjected to
different levels of preliminary fatigue loading ("damages"). These specimens were
subsequently subjected to vibration-assisted shot peening, or to surface cold working
with a roller, and then they were fatigue tested to failure on the same stress level as
that applied during preliminary fatigue loading. The analysis of the obtained data
showed that the surface cold-
