摘要：
Grain boundary diffusivity of chromium in SUS316 and 316L stainless steels has been determined in the temperature range between 5 18 and 1173 K. The magnitudes of the grain boundary diffusivities in four kinds of specimens are in the order of the cold-worked SUS316, the solution-treated SUS316L, the solution-treated SUS316 and the sensitized SUS316. The grain boundary diffusivities in these specimens are remarkably higher than those of previous works. The activation energies for the former are 85-91 kJmol(-1), whereas those for the latter are 151-234 kJmol(-1).
