摘　　要：高锰铝青铜(ZCuAl8Mn14Fe3Ni2)合金中Mn(13.5~15%)、Al(7.8~8.8%)、Fe(2.8~4.0%)、Ni(1.8~2.5%),各合金成分对组织转变均有影响。为方便研究,基于Al当量对比分析不同成分合金的相析出行为;通过连续升温试验研究组织演变规律及各相溶解情况。结果表明:各相析出温度受材料成分影响显著,高Al当量试样中α相析出温度较低;在连续升温试验中,β精细分解相在高温加热时可发生回溶,α相在700℃时完全溶解;加热温度高于800℃时,材料中只有基体β相和未溶解κ_(I)相。Mn(13.5~15%),Al(7.8~8.8%),Fe(2.8~4.0%)and Ni(1.8~2.5%)in high manganese aluminum bronze alloy(ZCuAl8Mn14Fe3Ni2)all have effects on the microstructure transformation.In order to facilitate the study,the phase precipitation behavior of alloys with different components is comparatively analyzed based on Al equivalent.The microstructure evolution law and dissolution of each phase were studied by continuous heating test.The results show that the precipitation temperature of each phase is significantly affected by the material composition,and the precipitation temperature of α phase in high Al equivalent samples is lower.In the continuous heating test,the β fine decomposition phase can be redissolved when heated at high temperature,and the α phase can be completely dissolved at 700℃.When the heating temperature is higher than 800℃,there are only matrix β phase and undissolved κ_(I) phase in the material.
