摘要：

The pressure-composition-temperature phase diagram for the absorption of hydrogen in the cubic Laves phase compound ErFe2 has been investigated. At least three stable hydrides ErFe2Hn are found with n ≈ 2, 3.4 and 4. At 20 °C, the equilibrium pressures for these phases are 0.04, 10 and 4000 Torr, respectively. The implications of these results on the preparation of samples for the measurement of physical properties is discussed. © 1979.
