摘要	Atomic images of delta-hydride and interphase boundaries between alpha-Ti and delta-hydride in Ti-H alloys containing 0.47 and 1.52 wt% H respectively, have been investigated by means of high resolution transmission electron microscopy (HRTEM). (0111BAR)alpha twins as well as (111)delta twins were generated due to a large volume expansion during hydride formation. The ledge structure can be observed at the (O111BAR)alpha twin interface with height n*d(0111BAR) (n = 2, 4, 6...). The interphase boundaries between alpha and delta are mostly semi-coherent and the distances between the misfit dislocations are consistent approximately with a geometrical analysis estimation. Two basic orientation relationships (O.R.) between matrix alpha and delta phases were defined and further two O.R.s were also derived from their twin structures.
