摘要：

针对现有铝合金材料和铸铁材料的不足之处，利用颗粒增强技术设计了一种高强度6XXX系铝合金材料，通过正交试验研究了高强度铝合金挂板锻造过程中打击能量、固溶温度和时效温度3项工艺参数对高强度铝合金挂板力学性能的影响规律，并通过抗拉强度和拉断力两个指标进行极差分析。结果表明，固溶温度和时效温度对力学性能的影响程度要远大于打击能量。对于拉断力的最佳工艺参数为：打击能量为20 kJ、固溶温度为535 ℃、时效温度为165 ℃；对于抗拉强度的最佳参数为：打击能量为25 kJ、固溶温度为545 ℃、时效温度为175 ℃。随着固溶温度的提高，高强度铝合金挂板的抗拉强度大幅增大，拉断力先显著提高后变化不明显；随着时效温度的提高，高强度铝合金挂板的拉断力及抗拉强度均有所下降。

Aiming at the shortcomings of existing aluminum alloy materials and cast iron materials, a high-strength 6-series aluminum alloy material was designed by using particle reinforcement technology. Then, through orthogonal experiment, the influence laws of three process parameters, namely, impact energy, solution temperature and aging temperature, on the mechanical properties of high-strength aluminum alloy panel during forging process were studied, and the range analysis was conducted by two indicators of tensile strength and tensile breaking force. The results show that the influence degrees of solution temperature and aging temperature on the mechanical properties are much greater than that of impact energy. The optimal process parameters for tensile breaking force are the impact energy of 20 kJ, the solution temperature of 535 ℃, and the aging temperature of 165 ℃. The optimal parameters for tensile strength are the impact energy of 25 kJ, the solid solution temperature of 545 ℃, and the aging temperature of 175 ℃. With the increasing of solid solution temperature, the tensile strength of high-strength aluminum alloy panel increases significantly, and the tensile breaking force first increases significantly and then changes insignificantly. As the aging temperature increases, the tensile breaking force and tensile strength of high-strength aluminum alloy panel both decrease.
