摘要：

Mg2Ni alloys with different crystallinities were prepared by mechanical alloying (MA), followed by a subsequent heat treatment and their charge-discharge characteristics in (6 M KOH + 1 M LiOH) aqueous solution were measured at 30 and 70 degrees C. At both temperatures, charge-discharge characteristics of the Mg2Ni prepared by MA came close to those of the Mg2Ni alloy prepared by induction melting (IM), with an increase in heat-treating period at 400 degrees C. The presented approach was believed to be very effective for the preparation of hydrogen storage alloys whose constituent metals have large differences in melting points.
