## Description

- description: The dynamics of hydrogen in metals with mixed grain structure is not
    well understood at a microscopic scale. One of the biggest issues facing the hydrogen
    economy is “hydrogen embrittlement” of metal induced by hydrogen entering and
    diffusing into the material. Hydrogen diffusion in metallic materials is difficult
    to grasp owing to the non-uniform compositions and structures of metal. Here a
    time-resolved “operando hydrogen microscope” was used to interpret local diffusion
    behaviour of hydrogen in the microstructure of a stainless steel with austenite
    and martensite structures. The martensite/austenite ratios differed in each local
    region of the sample. The path of hydrogen permeation was inferred from the time
    evolution of hydrogen permeation in several regions. We proposed a model of hydrogen
    diffusion in a dual-structure material and verified the validity of the model
    by simulations that took into account the transfer of hydrogen at the interfaces.
