By optimizing the mechanical properties of 6016 aluminum alloy automotive sheets,we aim to enhance their stability and durability in complex environments,thereby promoting the development of the aluminum alloy material processing and preparation industry.6016 aluminum alloy samples were prepared under different conditions by regulating the heat treatment forging process,including melting,annealing,extrusion,solution treatment,and aging treatment.Subsequently,the mechanical properties of the samples were systematically tested using a combination of heat treatment parameters,including a solid solution temperature of 180℃for 7 h,a first stage aging of 120℃for 2 h,and a second stage aging of 180℃for 4 h.The experimental results show that the aluminum alloy exhibits optimal performance under specific heat treatment conditions,including hardness of 105 HV,tensile strength of 242.25 MPa,yield strength of 274.51 MPa,elongation of 26.2%,bending strength of 310 MPa,and minimum bending deformation of 1.8 mm.This reveals the significant optimization effect of heat treatment forging process on the mechanical properties of 6016 aluminum alloy,and determines the optimal heat treatment parameters,providing theoretical and technical support for the preparation of high-performance aluminum alloy materials.
