铝及铝合金有强烈的吸氢特性,这一直是铝合金冶金中的一大难题。近年来不少冶金工作者证实,在熔融状态下的工业纯铝、Al-Si、Al-Cu合金中添加稀土对氢含量有影响。但至今未见有关室温下稀土对变形铝合金中氢含量影响的报道。本文采用电化学测氢法,准确测定了室温下金属中氢含量和氢行为的特点,研究了室温下工业纯铝和 Aluminum and aluminum have a strong hydrogen absorption characteristics, which has been a major problem in the aluminum alloy metallurgy. In recent years, many metallurgical workers have confirmed that the addition of rare earth to the industrial pure aluminum, Al-Si, Al-Cu alloys in molten state has an impact on the hydrogen content. However, no report on the effect of rare earth on hydrogen content in deformed aluminum alloy at room temperature has been reported so far. In this paper, electrochemical hydrogen measurement method, accurate determination of the metal hydrogen content and hydrogen behavior at room temperature characteristics of the room temperature industrial pure aluminum and
