In order to improve the properties of V-based solid solution hydrogen storage materials,ultrasonic stirring assisted casting method was used to prepare a new V-based solid solution hydrogen storage material V3 Ti Ni0.56Co0.1Al0.2.The phase compositions,microstructure,hydrogen absorption and desorption properties and corrosion resistance of the material were tested and analyzed.The results show that the new material consists of V-based solid solution phase,small amount of Ti Ni and Ti2 Ni phases,and it has favorable hydrogen absorption and desorption properties and corrosion resistance,of which the maximum hydrogen absorption capacity at room temperature is 1.781% and the plateau pressure of hydrogen desorption at room temperature is 0.46 MPa,and the corrosion potential shifts positively by 709 m V in comparison to V3 Ti Ni0.56.
