摘要
在495℃固溶保温50 min和175℃时效保温10 h工艺条件下,研究了停放时间对2024铝合金挤压型材力学性能的影响。实验结果表明:在该工艺条件下,淬火后停放8 h进行时效处理,2024铝合金挤压型材的屈服强度、抗拉强度、断后伸长率均达到最大值。结合实际生产效率,2024铝合金挤压型材淬火后应在8 h内进行时效处理。
The influence of delay time on the mechanical properties of 2024 aluminum alloy extrusion profiles is studied under solution treatment at 495 ℃ for 50 min,aging at 175 ℃ for 10 h. The results show that the yield strength,tensile strength,percentage elongation after fracture of 2024 aluminum alloy extrusion profiles reach the maximum under the process condition and aging after quenching and delayed for 8h. Combined with the actual production efficiency,the 2024 aluminum alloy extrusion profiles should be aging within 8 h after quenching.
