摘要	Hydrogen absorption can cause crystallographic changes in both alpha and beta phase of Ti alloy. To understand them better, the hydrogen diffusion behavior in Ti-5Al-5Mo-2V-2Cr-2Sn-2Zr dual-phase Ti alloy is investigated based on multi-scale characterization. The hydrogen distribution change of electrochemical hydrogen charging sample during aging at room temperature is characterized by neutron imaging technique. The hydride decomposition and hydrogen induced cracking are observed by interrupted in-situ method. Besides, the spinodal decomposition structure is observed in beta phase, which is widened by large lattice expansion due to hydrogen absorption. Finally, the interface of delta-hydride/alpha-Ti with the orientation relationship of {0001}alpha//{001}delta <1210>alpha//<110>delta is investigated. A new periodic structure formed by {1010} stacking faults is identified as intermediate state of hydride transformation.
