文摘

Hydrogen trapping mechanism of DSS was investigated using TDS and SIMS analyses. The relation between hydrogen distribution and trapping in DSS is discussed. ToF-SIMS for hydrogen's distribution supports hydrogen traps in DSS. Desorption analysis showed combined detrapped and diffusion controlled desorption. The γ→α′ phase transition was related to irreversible trapping site for hydrogen.
