Nano-crystalline Mg-10wt%Ni alloy can be achieved by melt-spinning.
Isothermal hydrogenation behaviors of modified Mg-rich alloys are investigated.
Synergetic catalytic effect of MWCNTs and TiF3 on hydrogenation is proposed.
Hydrogen content of modified Mg-10wt%Ni reaches to 5.29 wt% within 60 s at 250 °C.
