Abstract
No curvature is observed in the Arrhenius plot for nickel volume diffusion coefficients measured up to T=0.94Tm in Ni2Si using 63Ni as a tracer. Differential scanning calorimetry performed on the same samples, quenched from 820 and 1015°C, reveals two annealing stages, in good agreement with a previous positron annihilation study. The activation energy and the order of the reaction for each stage have been determined. At low temperatures, the activation energy of the stage centred at about 180°C (1.1 ± 0.leV) is integrated as the nickel monovacancy migration energy. It is assumed that the second stage, centred at about 380°C, corresponds to the break-up of vacancy clusters; its activation energy (2.6 ± 0.leV) is in agreement with that measured for nickel bulk diffusion (2.42 ± 0.04 eV).
