HydrogenSolubility
Computes the solubility of hydrogen in Zr cladding in (wt.ppm) and in (at.frac).
This object can be set up automatically by using the CladdingHydrides action.
Description
This material computes the hydrogen solubility used by HydrideGrowthKinetics, HydrideNucleationKinetics, HydridePrecipitationRate, and HydrideVolumeFraction.
Hydrogen Solubility
The solubility (or effective ) is given by:
where follows an Arrhenius law:
with J/mol and wt.ppm as default values (Lacroix, 2019; Lacroix et al., 2021; Passelaigue et al., 2021), and is a modifying function introduced in (Passelaigue et al., 2022) to account for the effect of the hydride volume fraction on :
with wt.ppm and as default values. The default fit with can be restored by setting wt.ppm and .
The solubility is also computed as an atomic fraction:
