The hydrogen solubility in solid binary aluminum alloys can be estimated by using exponential fits for Cu, Mg, Si, and Zn additions. Estimates show differences in hydrogen solubility between liquid and solid alloys, with some commercial alloys exhibiting unique behaviors.
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.
