| Popis: | Hydrogen solubility and diffusivity in HR-1 steel have been determined by a vacuum heating degassing technique at 597–1022 K on a set of specimens with different sizes previously charged for 24 h under a hydrogen pressure of 105 Pa in the temperature range of 800–1000 K. The permeability was then derived from the relation Φ = DKs. It is found that D = 1.52×10−6 exp(−54100/RT), Ks = 2.2×10−6 exp(−5400/RT), and Φ = 3.3×10−12 exp(−59500/RT) where Ks (Sieverts' constant) is given in Pa −1 2 , D in m2s−1, Φ in m2s−1 Pa −1 2 , T in K and R = 8.31 J gatoms−1K−1. |
