Tuning of Zr content in TiMn based multinary alloys by powder metallurgy to fabricate superior hydrogen storage properties.

TiMn based multinary alloys make full use of the high abundance of rare earth resources in attractive applications of hydrogen storage but suffer from mediocre hydrogen ab/desorption kinetics and lack the in-depth mechanism analysis of hydrogenation/dehydrogenation behavior. Herein, on the basis of current research on compositional modulation, we utilize the low-cost powder metallurgy method to prepare TiZrMnCrV (x = -0.05, 0, 0.
