Abstract

Hydrogen desorption associated with thermally induced α′ and ϵ martensitic transformations was characterized by cryogenic thermal desorption spectroscopy (C-TDS) during cooling. The utilization of a cooling process during C-TDS measurements revealed that the dominant factors in the hydrogen desorption related to the α′ and ϵ martensitic transformations were local changes in diffusivity and motions of transformation dislocations, respectively.
