Abstract
The electrical resistance isotherms have been measured during the interaction of hydrogen at T-9 Torr). It is shown that the typical points where the isotherm changes its slope correspond to the phase boundaries of the Er-H2 system, and that this agrees with present-day ideas on the role of interstitial hydrogen in the various phases. The use of evaporated films as samples has allowed the boundaries to be found down to 295K, and the alpha / alpha + beta ) boundary down to 130K. Previous experiments which used bulk samples substantially underestimated the room-temperature solubility limit of hydrogen in the metal.Keywords
