In this study, a series of Ti-Mg-Ni alloys have been synthesized by mechanical alloying using a planetary high-energy ball mill. The effect of varied composition on the microstructure and electrochemical hydrogenation properties of Ti-Mg-Ni system have been investigated through the compared analysis of Ti

alloys. The structural transformation and discharge capacities were characterized by XRD and electrochemical measurements at galvanostatic conditions, respectively. Additionally, a separate milling process has been employed for improving the electrochemical properties of Ti-Mg-Ni alloys. It is shown that the separated milling process can extremely enhance the discharge capacities of Ti-Mg-Ni composite materials.
