Abstract

By means of magnetic methods, in the Cu-jo.7a/o Ni-1. 6 a//o Fe alloy the Ostwald ripening of extremely small particles has been studied. It appears that the magnetic methods are very suitable for such investigations, as in addition to a high exactness, an easy way of execution is guaranteed. The chemical volume diffusion coefficients determined for 673 to 873 K are characterized by the Arrhenius parameters Do = 1.81 × 10−5 m2/s and ΔH = 219.4 kJ/mol.
