Abstract
The solubility of hydrogen in molten aluminum has been determined for temperature from 973 to 1073K, employing the rapid quenching method. The results closely agree with Van't Hoff isobar and represented by the equation for the solubility under hydrogen atmosphere of 101.3kPa: logS = 3.256-2392/T, where S is a solubility in the unit of cm3•kg-1, which means that the volume of hydrogen (at 273K, 101.3kPa) dissolved in the melt of 1kg, and T is the temperature of the melt in K. The results of present study show the considerably lower solubility compared with those from previous determinations adopted Sieverts' method.
