| Research Abstract |
In order to clarify mechanisms of hydrogen accumulation and release in/from metals, tritium tracer techniques are developed to measure amounts of released or permeated hydrogen from metals and distribution of hydrogen retained in metals. Applying these techniques, hydrogen diffusion and permeation coefficients in metals at low temperatures around room temperature are successfully determined for the first time.
