The results showed that substituting Ni with Al led to a desirable decrease in absorption/desorption plateau pressure as well as to hysteresis without a reduction in hydrogen capacity. However, Bi substitution reduced the hydrogen capacity and increased the absorption/desorption plateau pressure of the samples. The formation of the (Al,Ni) intermetallic and Bi phases at grain boundaries was found to be the main reason for the changes in hydrogen storage properties. © 2012 The Japan Society of Applied Physics.falseEffects of Substitution of Al and Bi for Ni on Structure and Hydrogen Storage Properties of LaNi <inf>4.7-x</inf>Al <inf>0.3</inf>Bi <inf>x</inf> (x = 0:1; 0:2; 0:3) AlloyEffects of Substitution of Al and Bi for Ni on Structure and Hydrogen Storage Properties of LaNi4.7-xAl0.3Bix (x=0.1, 0.2, 0.3) AlloyConference Paper10.1143/JJAP.51.09MB0110.1143/JJAP.51.09MB012-s2.0-84867691816WOS:00031070290000651
