| 中文摘要 | Interdiffusivity of the NiAl phase in Ni-Al binary system has been estimated as a function of composition in NiAl phase formed on pure nickel using the vapor-solid technique. The calculated results indicate that interdiffusivity in as-formed NiAl phase shows a minimum at about 48 at.% Al. deviating slightly from the stoichiometry. The fact can be explained by the concentration dependence of the thermodynamic factor and the creation of Al-vacancies on the Ni-rich side of stoichiometry. It is observed that activation energy for interdiffusion in the as-formed NiAl phase is particularly sensitive to the presence of constitutional vacancies, which is probably related to the lattice parameter of NiAl phase.
