The influence of Suction cast on phase structures and hydrogen storage properties of TiVCr based alloys has been investigated in this work. It is showed that suction cast is beneficial to the formation of a single solid solution phase with BCC structure resulting in the slight decrease of the lattice parameters. The slope coefficient Sf and the desorbing plateau pressure of the alloys were decreased and the capacity of absorption and desorption was increased by suction cast. Also, the activation performances of the alloys were reduced by suction cast. The desorbing plateau pressure and the capacity of desorption of the alloys increased with increasing Cr content.
