| Abstract: |
Understanding the influence of hydrogen on elastic deformation and anelastic response should contribute to our understanding of the influence of hydrogen on deformation and fracture. To accomplish this objective, samples of pure iron were cold-worked, charged with hydrogen, and examined in a dynamic mechanical analyzer. For these measurements, square wave loads were applied at different frequencies and the response of the sample quantified into time-independent and time-dependent components. These measurements were then analyzed to determine the influence of hydrogen on the time-independent, elastic, modulus and time-dependent, anelastic, relaxation. Hydrogen lowered the measured elastic modulus by a small, but statistically significant, amount. |
