摘　　要：使用高温气雾化法制备了Al-40Mg、Al-37Mg-3Li与Al-37Mg-3Eu (wt.%)三种合金燃料粉末,用XRD和SEM表征其物相组成和表面形貌,并研究了Al-40Mg、Al-37Mg-3Li与Al-37Mg-3Eu三种合金燃料粉末在高压反应釜中的水反应性能。结果表明,单质Al粉的产氢效率仅为80.17%,而Al-40Mg、Al-37Mg-3Li、Al-37Mg-3Eu的产氢效率分别提升至93.69%、94.32%和94.63%。此外,还表征了三种合金燃料粉末水反应产物的物相组成和微观形貌。Al-40Mg, Al-37Mg-3Li and Al-37Mg-3Eu (wt.%) alloy fuel powders were prepared by high tempera-ture gas atomization method, and their phase compositions and surface morphology were charac-terized by XRD and SEM. The water reaction properties of Al-40Mg, Al-37Mg-3Li and Al-37Mg-3Eu alloy fuel powders in high pressure reactor were studied. The results showed that the hydrogen production efficiency of elemental Al powder was only 80.17%, while the hydrogen production effi-ciency of Al-40Mg, Al-37Mg-3Li and Al-37Mg-3Eu increased to 93.69%, 94.32% and 94.63%, re-spectively. In addition, the phase composition and morphology of the water reaction products of three kinds of alloy fuel powder were characterized.
