... is usually much larger than the relatively small surface energy (about 1000 to 1). Thus, even a large reduction in surface energy due to hydrogen adsorption should not markedly affect the fracture stress. Another discrepancy is that other environmental species, such as oxygen and nitrogen, also strongly...
