ABSTRACT

The solubility of hydrogen in solid binary aluminium alloys has been investigated with data from the literature. As in liquid binary alloys, analysis has shown the effect of Cu, Mg, Si and Zn additions on normalised hydrogen solubility can be estimated by using exponential fits. The method developed previously to estimate hydrogen solubility in liquid commercial alloys has been extended to alloys in their solid state. Estimates for hydrogen solubility at the liquidus and solidus temperatures for five commercial alloys have been calculated. Estimates of the hydrogen solubility difference between liquid and solid alloys have shown that (i) the 206 alloy behaves exactly like pure aluminium (ii) 319 and A356 have much lower differences than pure aluminium, and (iii) hydrogen solubility at the solidus temperature is higher than at the liquidus temperature in alloy 380 and 383.

摘要

已经用文献数据研究了氢在固体二元铝合金中的溶解度。与液态二元合金一样，分析表明添加 Cu、Mg、Si 和 Zn 对归一化氢溶解度的影响可以通过指数拟合来估计。先前开发的用于估计液态商业合金中氢溶解度的方法已扩展到固态合金。已经计算了五种商业合金在液相线和固相线温度下的氢溶解度估计值。对液态合金和固态合金之间的氢溶解度差异的估计表明 (i) 206 合金的行为与纯铝完全一样 (ii) 319 和 A356 的差异比纯铝小得多，
