Abstract
AbstractThe solubility of hydrogen in liquid pure aluminium has been redetermined for temperatures from 943 to 1123 K and pressures from 67 to 113 kPa (0·66 to 1·12 atm), using an appropriate version of Sieverts' method. The results fit the Van't Hoff isobar and Sieverts' isotherm. Recommended values for the solubility (S) are given, based on critical assessment of both the present results and corresponding results from recent previous determinations. The recommended values are given by the equation log(S/S°)−1/2log(p/p°)=(−2700/T)+2·72, where S° is a standard value of solubility equal to 1 cm3 of diatomic hydrogen measured at 273 K and 101·325 kPa (1 atm) per 100 g of metal, p° is a standard pressure equal to 101·325 kPa (1 atm), and T is absolute temperature.MST/502
