英文摘要	Six kinds of Al-Ga-Mg-Sn multi-element aluminum alloys with different compositions were prepared by crucible resistance furnace. The microstructure and phase composition of as-cast aluminum alloy, the phase composition of the hydrolyzate, the hydrogen generation rate and hydrogen yield in pure water at 30, 50, 70 and 90 were investigated by means of optical microscope (OM), scanning electron microscopy (SEM), X-ray diffraction (XRD) and hydrogen generation performance test device. The results indicate that the as-cast Al-Ga-Mg-Sn multi-phase aluminum alloy consists of an aluminum matrix phase, Mg2Sn and Ga2Mg phases and the hydrolyzate is mainly AlO(OH).The hydrogen generation rate and hydrogen yield increase with the increment of temperature for the same composition. At the same temperature, for the samples with different compositions, the content of the low melting point element Ga, the proportion of the aluminum matrix phase and the second phase in the alloy phase depend on the hydrogen generation rate and hydrogen yield. The starting temperature of hydrogen generation is mainly determined by the content of low melting point elements Ga and Sn. Further analysis finds that the hydrogen generation rate k and thermodynamic temperature T obey Arrhenius formula, namely the ln k is linear with 1/T after hydrogen generation by hydrolysis occurring. © 2019, Science Press.
