Abstract

Simulation and experimental study of asymmetrical quenching processes were carried out on 7075 Al alloy thick plates. Effects of heat transfer coefficient ratios, thicknesses, and widths on warping deformation by asymmetrical quenching were simulated, and an increasing heat transfer coefficient ratios and plate thickness would obviously deteriorate plate-shape quality while plate width has fewer influences on both residual stresses and warping deformation. Experiments on one-side water spraying quenching were carried out to evaluate detailed relationship between warping deformation and residual stresses under different supporting patterns. The maximum plate irregularities always occur around its supporting locations and then expand far away and more supporting locations could reduce quenching deformations. The warping deformation during quenching is essentially caused by internal residual stresses introduced by heterogeneous heat exchanging, and the external structural warping deformation would respond reasonably to the internal residual stresses distribution.
