摘　　要：本文采用正交试验研究了固溶强化和时效处理对热挤压态铜镍锡合金力学性能的影响,并使用正交试验极差分析法得出最佳工艺参数。结果表明,固溶温度、时效温度和时效时间对铜镍锡合金的硬度、抗拉强度和断后伸长率的影响均存在差异。铜镍锡合金硬度、抗拉强度和塑性都较为优良时的热处理工艺参数组合为:775℃固溶×1 h+水淬+380℃时效×5 h(水冷降温),与铜镍锡合金原材料相比,经热处理工艺参数优化后的铜镍锡合金的硬度和抗拉强度提升,伸长率降低。The effects of solution strengthening and aging treatment on the mechanical properties of hot extrudated copper-nickel-tin alloys were studied by orthogonal test,and the optimal process parameters were obtained by range analysis of orthogonal test.The results show that the effects of solution temperature,aging temperature and aging time on the hardness,tensile strength and elongation of copper-nickel-tin alloy are different.When the hardness,tensile strength and plasticity of copper-nickel-tin alloy are relatively good,the combination of heat treatment process parameters is as follows:775℃solid solution×1 h+water quenching+380℃aging×5 h(water cooling),compared with the copper-nickel-tin alloy raw materials,the hardness and tensile strength of copper-nickel-tin alloy after heat treatment process parameters optimization are increased,and the elongation is reduced.
