Energetics and structures of hydrogen-vacancy clusters in tungsten based on genetic algorithm
The behavior of hydrogen (H) in metals has been a longstanding research topic in materials science.One of the most compelling subjects is the deleterious effects of H on the microstructural evolution of materials;these effects include H embrittlement,superabundant vacancy formation,and blistering.Vacancies have been demonstrated through both experiments and computational simulations to have strong H trapping effects ”1”,resulting in increased H retention ”2”,gas-filled bubble formation ”3-5”,and surface modification ”6-9”.
