## Description

- description: One of the biggest issues in 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 behavior 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.
