摘　　要：采用机械球磨法制备了铝锡系列合金.水解制氢曲线和XRD结果表明,添加剂(锌和氢化物)的加入和球磨时间的延长,有利于金属铝和金属锡的均匀混合和活性一致.常温下该系列合金与水反应迅速,氢气产量高.尤其是球磨10h的Al-10%Sn-5%Zn-5%MgH2(质量分数)合金,在10min内水解反应结束,氢气产量为785mL/g,水解速率为78.5mL/(min·g).In this paper the Al-Sn materials were firstly prepared by the mechanical alloying. The results of the hydrogen-produced curves and X-ray diffraction patterns show that the additives （Zn or hydride） and the prolonged milling time favor to make the composition blend uniformly. The milled materials have good hydrolysis properties in water at room temperature, especially that the Al-10% Sn-5% Zn-5% MgH2 （mass fraction） material milled for 10 h produced 785 mL/g with the hydrogen generation rate of 78.5 mL H2/（min · g）.
