摘要: An AISI 430 (UNS S43000) stainless steel sheet was cold-rolled and then annealed at 1,073 K, to derive three different grain sizes. Through Devanathan hydrogen permeation tests at 303 K and a mathematical analysis for diffusion in laminate structures, the grain boundary diffusion coefficient (D-g = 1.14 x 10(-15) cm(2)/s) and the lattice diffusion coefficient (D-l = 2.88 x 10(-6) cm(2)/s) were determined. The grain boundary was found to be a diffusion barrier. This result strongly supported the most important assumption in the mathematical analysis.
