摘要:
Melt spinning (MS) and ball milling (BM) were employed to fabricate YMg11Ni alloy,and their structures and hydrogen storage performances were examined.The results reveal that the as-spun and as-milled alloys both exhibit the nanocrystalline and amorphous structure.The as-milled alloy shows a larger hydrogen absorption capacity as compared with the as-spun alloy.More than that,the as-milled alloy exhibits lower onset hydrogen desorption temperature than the as-spun one,which are 549.8 and 560.9 K,respectively.Additionally,the as-milled alloy shows a superior hydrogen desorption property to the as-spun one.On the basis of the time needed by desorbing hydrogen of 3 wt% H2,for the asmilled alloy,it needs 1106,456,343,and 180 s corresponding to hydrogen desorption temperatures of 593,613,633,and 653 K.However,for the as-spun alloy,the time needed is greater than 2928,842,356,and 197 s corresponding to the same temperatures.Hydrogen desorption activation energies of as-milled and as-spun alloys are 98.01 and 105.49 kJ/mol,respectively,which is responsible for that the as-milled alloy possesses a much faster dehydriding rate.By means of the measurement of pressure-composition-temperature (P-C-T) curves,the dehydrogenation enthalpy change of the alloys prepared by MS (△Hde(MS)) and BM (△Hde(BM)) is 81.84 and 79.46 kJ/mol,respectively,viz.△Hde(MS) > △Hde(BM).
