中文摘要: 采用真空感应熔炼的方法制备了NiCoCrAlY合金锭，并对合金的铸态显微组织进行了研究。结果表明： NiCoCrAlY铸态合金主要由4个相组成，分别为γ相、γˊ相、Y富集相及共晶组织β+γˊ。其中Y富集相为Ni3.55Co0.5Cr0.2Al0.75Y，以网状形式偏聚于γ相周围；共晶组织中β相为(Ni,Co)Al，γˊ为(Ni,Co)3Al，且γˊ呈圆棒状镶嵌在β相中。
Abstract:The NiCoCrAlY alloy ingot is prepared by vacuum induction melting. Then the cast microstructure is studied. The result shows that NiCoCrAlY cast alloy is mainly composed of four phases, namely γ-phase, γˊ-phase, Y-rich phase and eutectic β+γˊ. Y-rich phase is Ni3.55Co0.5Cr0.2Al0.75Y, surrounding γ phase in the form of mesh. β and γˊare (Ni,Co)Al and (Ni,Co)3Al respectively, and γˊphase is embedded in the β phase as cylindrical rods in the eutectic.
