Abstract

Chemical diffusion coefficient in the L1₂ ordered compound Ir₃Nb has been measured by single-phase interdiffusion experiments in the temperature range from 1750 to 1950°C. The diffusion coefficient is described by the pre-exponential factor of 10^-5.3±1.1 m ²s^-1 and the activation energy of 4.83±0.44eV.
