摘      要：Effects of hydrogenation on ambient deformation behaviors of Ti-45Al alloy were *** stress-strain curves demonstrate that the plastic deformation of the hydrogenated alloys becomes more remarkable than that of the unhydrogenated alloy. Meanwhile,the compression strength and maximum strain are *** the hydride and hydrogen atoms in the interstices affect the compression deformation *** reason of the hydrogen-induced embrittlement is that the hydride is easy to become the nucleus of the *** the variation of plastic deformation process is attributed to hydrogen-promoted emission,multiplication and motion of dislocation.
