Hydrogen Diffusion in Ti-Cr Hydrogen Absorption Alloys by Tritium Radioluminography

Abstract:

Article Preview

Tritium radioluminography has been applied to Ti50Cr50 and Ti40Cr60 alloys with two-phase structure of BCC phase and Laves phase by examining hydrogen distributions and by measuring a hydrogen penetration profiles. Hydrogen diffusion coefficients in these alloys have been successfully determined by analyzing the tritium depth profile to be 3.3×10-12 m2/s and 1.3× 10-12 m2/s, respectively. This value has been suggested that the hydrogen diffusion in the Laves phase is slower than that in the BCC phase.
