Notes:
The elastic constants of a well-characterized, high-purity single crystal were measured before and after hydrogen was added to change the hydrogen content from 500 at. ppm (3 wt. ppm) to 6900 at. ppm (40 wt. ppm). Comparison between the two sets of measurements shows that such a small change in hydrogen content has a disproportionately large effect on the elastic stiffness. In this case the increase in hydrogen content produced an increase in all directly measured elastic constants by the order of 0.5%. Further comparison of our data with earlier data indicates that other interstitial elements (e.g., C, N, and O) may also exert an inordinately large influence on the elastic stiffness.
