## Description

- description: We have improved an electron stimulated desorption (ESD) apparatus
    to obtain the time evolution of hydrogen permeation for cold-worked stainless
    steel. Hydrogen permeation through grain structures was visualized by using the
    operando hydrogen microscope combining ESD and hydrogen supply system. The diffusion
    coefficients in grains were calculated from time evolution curves of hydrogen
    permeation. Principal component analysis (PCA) of hydrogen maps was used to classify
    crystal grains by the degrees of hydrogen diffusion and permeation flux. Grain
    structures such as the ratio of austenite/martensite, crystallographic orientations
    and coherent/random grain boundaries were determined by electron backscatter diffraction
    (EBSD) analysis. The areas with high-speed and high flux permeation of hydrogen
    were characterized as smaller austenitic grains with grain boundaries. The usefulness
    of a combined ESD-PCA-EBSD analysis on hydrogen permeation in materials was demonstrated
    in the present study.
