英文摘要ternary alloys mg(45)m(5)co(50)(m= zr, ni, al) were synthesized by mechanical alloying technique to improve the hydrogen storage properties of mg(50)co(50) binary body centered cubic (bcc) alloy. x-ray diffraction (xrd) revealed that the bragg peaks of these alloys were broadened, which indicated that the crystalline size of these alloys was fully pulverized. both bcc phase and amorphous phase in the ternary alloys were found after ball milling for more than 80 h by transmission electron micrograph (tem). with the increase of ball milling time, however, the bcc phase disappears gradually and the amorphous phase dominated the alloys eventually. pressure-composition-isotherms (p-c-t) measurements showed that these ternary alloys containing bcc phase can absorb hydrogen at 353 k within the hydrogen pressure range of 0 similar to 3 mpa. mg(45)al(5)co(50) alloy had the maximum hydrogen absorption amount (2.0 wt. %) among these ternary alloys. moreover, ternary mg45al5co50 alloy exhibited better hydrogenation kinetics than binary mg(50)co(50) alloy. the former took about 30 h to reach the maximum capacity, which is faster than the latter of 40 h. the third elements ni and zr improve the hydrogen desorption properties of mg(50)co(50) alloy which hardly desorbs any hydrogen. tg analysis showed that mg(45)ni(5)co(50) and mg(45)zr(5)co(50) can desorb hydrogen 0.5 wt. % at 350 k and 1.0 wt. % at 470 k, respectively.
