摘　　要：通过X射线衍射分析、金相观察及力学性能测试 ,研究了Cu 2 8Zn 15Ni 13Mn合金形变热处理过程中的组织变化 ,分析了微合金化及变形量对力学性能的影响。结果表明 ,当添加量 (质量分数 ,% )为 :① 0 .187Al+0 0 13Ce +0 2 4Fe +0 1Zr +0 1Ti +0 1B ,② 0 5Ti时 ,宜采用 85 %的冷变形 ,此时微合金化可提高冷变形态及微双相态的强度性能。微双相态时以①方式添加强化效果更好。添加 0 1Ti、0 5Zr或不添加微量元素时 ,变形量从 85 %增大到 90 % ,将使微双相态的比例极限、屈服极限有所提高。The structural change of Cu-28Zn-15Ni-13Mn was studied by XRD and OM and the effect of trace elements and cold deformation on mechanical properties was studied by the tensile test. The results show that with the addition of trace elements (mass%) such as (1) 0.187Al + 0.013Ce + 0.24Fe + 0.1Zr + 0.1Ti + 0.1B, (2) 0.5Ti, the suitable cold strain was 85%, leading to improve the strength in both cold deformation state and microduplexed state. In microduplexed state, the strengthing effect of the former (1) was better. The mechanical properties of partially recrystallized samples and microduplexed samples were similar.
