MEASUREMENT OF IRON DIFFUSION IN AN Fe-3% Si ALLOY BY MEANS OF THE MÖSSBAUER TECHNIQUE

Abstract

Iron diffusion in an Fe‐3% Si alloy has been studied by means of the Mössbauer effect. The results in this iron‐base system agree closely with conventional measurements and do not appear to exhibit the factor of 2 anomaly with the Singwi and Sjölander analysis which Knauer and Mullen observed for iron in dilute solution. The values obtained can be described by the equation $${\text{D=0.20(}}_{-}^{\text{0.15;+0.65}}\mathrm{)\hspace{0.17em}}\exp \text{[−49\hspace{0.17em}600±3700/RT]}$$ .
