主 题：conveyor velocity roller table residual stress finite element thermal-mechanical simulation aluminum alloy thick plate
摘 要：Solution heat treatment combined with a rapid quenching operation,which can effectively suppress the decomposition of the supersaturated solid solution in the matrix,is a vital process step for producing large precipitation-hardenable aluminum alloy thick plates with desired ***,large thermal gradients that result from the non-uniform cooling rates during quenching usually give rise to severely heterogeneous distributions of residual stress in thick *** presence of roller-hearth furnaces makes it possible to achieve continuous and integral solution-quenching treatment for large aluminum alloy thick *** conveyor velocity of the roller table in the roller-hearth furnace is a key parameter but its influence is less addressed in ***,in the present work,finite element thermal-mechanical simulations taking into account different conveyor velocities of the roller table were employed to predict the temperature variations and residual stress distributions in large aluminum alloy thick plates during quenching *** different velocities were utilized in the *** modeling results showed that the temperature evolutions as well as the distributions of the induced internal stresses in those large thick plates during quenching treatments were indeed affected by the conveyor *** velocities were demonstrated to be favorable for gaining thick plates being with relatively homogeneous residual stress distributions in the plates.
