Self-diffusion in high-purity iron (99.97 per cent Fe) has been determined over the temperature r8nge from 700 to 1438ยฐC. The temperature dependence of the self-diffusion coefficient in fete-centered cubic and in body-centered cubic iron can be expressed as follows (in cm\*/sec): ## Gamma -iron:

Surface dissolution is thus expected to be faster in such localities. The probability of occurrence of dissolution figures on cold-worked samples is therefore likely to increase partly because of the increased number of dislocation sites on the surface, and partly because of the annealing out of the
The grain boundary self-diffusion coefficient D gb in high purity iron was measured by a serial sectioning method with radioactive tracer 59 Fe in the temperature range between 523 and 703 K using type-C kinetics. Furthermore, the grain boundary self-diffusivity dD gb was measured between 873 and 11
