Abstract Scope |
The purpose of this article is to better understand the behaviour of the residual stresses in aluminium alloy plates, to control and minimize them by adjusting the quenching and the stretching process parameters. The evolution of the residual stresses in the aluminium plates and the influence of the quenching and stretching process conditions was investigated by the Hole-Drilling method. The experiments were performed only on the industrial equipments. Plates with the same chemical composition were quenched by water spray or by immersion in water with or without agitation of the cooling medium. Also the plates quenched by water spray were unidirectional, bidirectional and successive stretchered. The results show the influence of the quenching conditions and of the stretching rate on residual stresses and also the correlation between the stretch rate and the residual stresses was established. |
