摘　　要：通过力学性能检测及金相组织观察,研究微量Mn的添加对纯铜组织及力学性能的影响。结果表明:在纯铜中添加微量Mn可以提高纯铜的强度,随着Mn加入量的增加制冷铜管的强度随之变高。并且发现,Mn在纯铜中分布不均,导致Cu-Mn合金再结晶不完全.The influence of Mn content on the microstructure and mechanical properties of Air-conditioning and refrigeration copper tube was studied by using metallographic observation and mechanical property measurement.The results showed that the addition of Mn to copper alloys increased their strength.It was also found that the incomplete recrystallization of the Cu-Mn alloy may be due to the inhomogeneous distribution of Mn.
