铝及铝合金熔体具有容易吸气的特点,在所吸收的气体中主要是氢。根据气体分析,大气中氢的分压极低(约5×10~(-5)大气压),铝中氢的主要来源是铝与水蒸气的反应生成物。氢在液态金属铝中的溶解度为0.69厘米~3/100
Aluminum and aluminum alloy melt with easy to inhale the characteristics of the absorption of gas is mainly hydrogen. According to the gas analysis, the partial pressure of hydrogen in the atmosphere is extremely low (about 5 × 10 -5 atmospheric pressure). The main source of hydrogen in aluminum is the reaction product of aluminum and water vapor. The solubility of hydrogen in liquid aluminum is 0.69 cm -3/100
