Isothermal compression tests were carried out on the Ti-5.6Al-4.8Sn-2.0Zr-1.0Mo alloy with and without hydrogen. A series of experiments including the optical microstructure and TEM (Transmission Electron Microscope) were performed to the compressed samples. The results show that hydrogenation not only increases the fraction ofβ phase, but also activates the propagation of the dislocation and formation of the twins, which are benefit for plastic or superplastic formability.
