摘要

摘要利用文献资料研究了氢在固态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氢在液态商业合金中溶解度的方法已扩展到固态合金。对五种商用合金在液相线和固相线温度下的氢溶解度进行了估算。对液体和固体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相似（ii）319和A356具有比纯铝低得多的差异，以及（iii）合金380和383中在固相线温度下的氢溶解度高于在液相线温度下。

On estimating the hydrogen solubility in solid aluminium alloys and the hydrogen solubility difference between the liquidus and solidus temperatures

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.

期刊介绍： The International Journal of Cast Metals Research is devoted to the dissemination of peer reviewed information on the science and engineering of cast metals, solidification and casting processes. Assured production of high integrity castings requires an integrated approach that optimises casting, mould and gating design; mould materials and binders; alloy composition and microstructure; metal melting, modification and handling; dimensional control; and finishing and post-treatment of the casting. The Journal reports advances in both the fundamental science and materials and production engineering contributing to the successful manufacture of fit for purpose castings.
