中文摘要：
采用微观相场法研究高Al浓度Ni75AkV25。合金析出相Ni3Al的反位缺陷随Al浓度增高的变化规律。选取在1150K温度下时效从8at％Al至20at％Al的共14个合金作为研究对象。研究结果显示：此类型合金主要反位缺陷类型是VAl、NiAl；随Al浓度增高，反位缺陷AlNi增高；而NiAl、VAl、VNi3种反位缺陷变化与Al浓度和Ni3v析出与否相关，Al浓度稍低时，有Ni3V相析出，Al浓度增高反位缺陷NiAl降低，VNi升高，VAl没变化：Al浓度稍高时，无Ni3V相析出，Al浓度增高反位缺陷NiAl稍有降低，VNi、VAl明显降低。
英文摘要：
The microscopic phase-field method was employed to study the antisite defect of Ni3A1 which precipitated from high Al concentration Ni75AlxV25-xalloy. Result shows that the main antisite defect type of this alloy are VAl, NiAl; with the increasing of Al concentra-tion, the AlNi antisite defect also increases; while changes of the other three types antisite defect NiAl, VAl, and VNi are slightly complex for its dependence on the precipitation or not of Ni3V phase; at comparatively lower Al concentration, when there is Ni3V phase, NiAl decrease with elevated Al concentration, while VNi increase and VAl keeps unconverted; at comparatively higher Al concentration, when there is no Ni3V phase precipitated from the matrix, NiAl slightly decreases with elevated Al concentration while VNi and VAl decrease sharply.
