摘要(Abstract)：

利用传统熔铸法制备了Cu-15Ni-8Sn和Cu-15Ni-8Sn-0.57Y合金，通过光学显微镜(OM)、扫描电镜(SEM)和直读光谱仪等研究了Y元素对铸态Cu-15Ni-8Sn合金的组织、力学性能和Sn元素分布的影响。结果表明：添加Y能细化铸态Cu-15Ni-8Sn合金的枝晶形貌，使合金中层片状过渡组织(α+γ相)减少，并且可以抑制Sn元素的宏观偏析，铸锭中部和下部Sn元素宏观偏析程度分别改善了28%和9%;此外添加Y元素后，Cu-15Ni-8Sn合金硬度由108 HB增加到116.3 HB,导电率由9.834%IACS下降到6.634%IACS。

关键词(KeyWords)： Cu-15Ni-8Sn合金;稀土Y;显微组织;宏观偏析
