摘要(Abstract)：

提高Ta、W元素的含量是新型镍基粉末高温合金设计和研究的趋势。为了研究Ta、W元素交互作用对粉末高温合金组织的影响，设计了一种高(W+Ta)的粉末高温合金，在保持(W+Ta)的总量(7.5%,质量分数)和其他元素含量相同的情况下，合金的Ta/W比从4.0/3.5逐步下降到3.0/4.5。结果表明：Ta/W比的变化对合金的晶粒组织基本没有影响，对碳化物、γ′相的分布和含量影响不大，但强烈影响二次γ′相的形貌和尺寸。随Ta/W比的下降，二次γ′相的尺寸逐渐增大，形貌由近方形转变为不规则形状，甚至产生分裂趋势；γ′相和γ基体的晶格常数均减小，但γ基体晶格常数减小更多，导致合金γ′相/γ基体间错配度增大。W元素随着Ta/W比的降低从倾向分配在γ基体转变为分布在γ′相；除W外，Ta/W比对其他合金元素在γ′相/γ基体间的分配系数影响不大。

关键词(KeyWords)： 镍基粉末高温合金;显微组织;相组成;元素分配;Ta/W比
