    <title language="eng">Modeling interdiffusion processes in CMSX-10/Ni diffusion couple</title>
    <abstract language="eng">A diffusion couple between directionally solidiﬁed nickel and the single crystal Ni-base superalloy CMSX-10 was produced by hot pressing in vacuum. The diffusion couples were heat treated at temperatures between 1050 and 1250 °C. The exposed samples were characterized by SEM/EBSD/EPMA. The interdiffusion results in dissolution of the c¢-Ni3 Al in the superalloy and in growth of nickel grains towards CMSX-10. Rapid diffusion of aluminum from the superalloy into pure nickel leads to a signiﬁcant formation of pores in the superalloy. The interdiffusion processes were modelled using the ﬁnite-element simulation software DICTRA with the databases TCNi5 and MobNi2, tailored specially for Ni-base superalloys. The effect of alloying elements on the interdiffusion proﬁles is discussed in terms of alloy thermodynamics. The calculated element concentration proﬁles are in good agreement with the EPMA measurements.&#13;
The interdiffusion modeling correctly predicts the shapes of the concentration proﬁles, e.g. kinks on the Al and Ti proﬁles in the vicinity of the original interface in the joint. The calculation predicts with reasonable accuracy the extent and the location of the Kirkendall porosity.</abstract>
