Resumen:
We present a study of the atomic scale deformation mechanisms occurring at the crack tip in hcp Zr with and without a dilute amount of H present.Mode I crack propagation was studied using EAM potentials and atomistic simulation techniques. The results show a variety of deformation mechanisms, including twinning and hcp to bcc phase transformations near the crack tip. H impurities were placed at different the various deformation mechanisms involved in the crack propagation to bcc transformation region leading to an increase in ductility in some single crystal configurations.
