    摘要:

    采用真空電弧熔煉制備了Ni-34Al-32V(at.%)及Ni-28.5Al-43V(at.%)成分的合金。對(duì)于真空電弧熔煉紐扣錠不同位置處微觀組織及力學(xué)性能進(jìn)行了研究。利用光學(xué)顯微鏡（OM），X射線衍射（XRD），掃描電鏡（SEM） 分析了合金不同凝固位置處的相組成和組織形態(tài), 結(jié)果表明，32V合金的凝固組織由NiAl初生枝晶及NiAl+V片層共晶組成；43V合金的凝固組織由V初生枝晶與NiAl+V片層共晶共同組成。同時(shí)對(duì)合金進(jìn)行了力學(xué)性能測(cè)試，高溫壓縮強(qiáng)度與室溫?cái)嗔秧g性較NiAl合金均有很大提高，表明V的加入可提高NiAl合金的室溫?cái)嗔秧g性與高溫強(qiáng)度。

    Abstract:

    The ternary alloy of Ni-34Al-32V(at%) and Ni-28.5Al-43V were prepared with success by vacuum non-consumable arc melting.The various locations of alloy solidified microstructure and compression behavior were investigated by using optical microscope(OM), X-ray diffraction(XRD) as well as scanning electron microscope (SEM).The results show that the solidified microstructure of the ternary alloy NiAl-32V was mainlly composed of the NiAl primary phases and NiAl+V eutectic.Meanswhile, the NiAl-43V was mainlly composed of the V primary phases and NiAl+V eutectic.At the same time, the mechanical properties of these two alloys were tested.From the fact, the compressive properties at room and elevated temperatures of the two composites are much higher than those of NiAl alloy.According the fact that V additions can remarkably improve the room-temperature fracture toughness and the elevated temperature strength of the NiAl-V alloy.
