摘要：
Annihilation stages of lattice defects induced into LaNi5 during hydrogenation were analyzed by differential scanning calorimetry from 300 to 1200 K. Five irreversible exothermic peaks were observed. They correspond to the annihilation of vacancy clusters at lower temperatures and of dislocations at higher temperatures in LaNi5. (c) 2005 Elsevier B.V. All rights reserved.
