Elastic fields generated by a semi-spherical hydride particle on a free surface of a metal and their effect on its growth

▶ The elastic fields set up by a semi-spherical hydride particle growing at a free surface of a metal with cubic symmetry, with and without an oxide layer are studied in detail. ▶ The elastic fields are correlated with the three stages along the microstructural evolution of some hydride forming metals exposed to hydrogen at constant pressure, which were described experimentally.
