摘要：

Mutual diffusion experiments were performed between Ni3Al and Ni3Ge diffusion couples. From the marker movement the intrinsic diffusion coefficients were evaluated. In addition volume diffusion of Ni-63 tracer in the ternary Ni-3(AlGe) compounds has been measured. Furthermore we present an approach based on a relation between the intrinsic and tracer diffusivities which was used to estimate the Al diffusivity.
