近年来,诸如全球变暖、化石燃料枯竭等环境问题日趋严重。发展使用氢作为清洁能源的燃料电池汽车,受到了汽车制造商的广泛重视。铝合金已经应用到燃料汽车的高压氢气槽的衬垫材料中。然而,氢在铝合金中的反应仍然没有得到清楚的阐明。因此,有必要分析氢在铝合金中的反应。氢缩影技术(HMPT)一直被视为一种探讨铝合金中氢行为的有效措施。目前,在室温下采用HMPT技术研究了拉伸变形Al-9%Mg合金内部氢析出的过程,发现氢在一些晶界处析出。
In recent years, environmental issues such as global warming and the depletion of fossil fuels have become increasingly serious. The development of fuel cell vehicles that use hydrogen as their clean energy has drawn the attention of car manufacturers. Aluminum alloys have been applied to the gasket material of high pressure hydrogen tanks in fuel vehicles. However, the reaction of hydrogen in aluminum alloys has not been clearly elucidated. Therefore, it is necessary to analyze the reaction of hydrogen in the aluminum alloy. Hydrogen shrinkage (HMPT) has long been regarded as an effective measure to investigate hydrogen behavior in aluminum alloys. At present, HMPT was used to study the internal hydrogen evolution in Al-9% Mg alloy during tensile deformation. Hydrogen was found to precipitate at some grain boundaries.
