摘要 For further improving the rate properties of Nd0.8Mg0.2(Ni0.8Co0.2)3.8 hydrogen storage alloy,the alloy was annealed in high mag-netic fields(10 T).The results showed that the electrochemical properties and magnetic properties of Nd0.8Mg0.2(Ni0.8Co0.2)3.8 hydrogen storage alloy were considerably enhanced.And there was no change of the phase composition.The lattice constants of c and c/a ratio increased for the sample magnetically annealed,yielding uniaxial magnetic anisotropy along the c axis.The increase o...
