综述了Ni-Al二元系、Ni-Cr-Al三元系、Ni-Co-Cr-Al四元系NiAl相的化学互扩散系数,并在此基础上,借助DICTRA软件的PARROT模块,构建了NiAl相的扩散迁移率数据库,以计算多元系NiAl相的化学互扩散系数。
The chemical interdiffusion coefficient of Ni-Al binary system, Ni-Cr-Al ternary system and Ni-Co-Cr-Al quaternary system NiAl phase are reviewed. Based on this, the PARROT module of DICTRA software is used to construct The diffusion mobility database of NiAl phase was used to calculate the chemical interdiffusion coefficient of NiAl multiphase.
