摘要	Cyclic testes were conducted on commercially pure titanium with low hydrogen concentration, in which gamma hydrides dispersed homogenously. It was found that dislocations can transfer through the coherent interface only before the hydride was fragmented, after fragmentation, dislocations would tangle at the fragments and do not penetrate the interface again due to the decrease of the maximum stress in the fragments. At least three sets of dislocations can be activated in hydrides during the cyclic deformation. To accommodate the inhomogenous strain between the matrix and hydrides, the crystal rotation occurred in both of them. A mechanism for the crystal rotation has been proposed.
