摘要：

Hydrogen sorption properties of Mg + 5wt.%Cr2O3 mixtures are examined. Increasing the milling injected power enhances the hydriding rates. The higher sorption rates (1.32x10(-2) wt.%/s at 300degreesC for desorption) are obtained for planetary ball mill, high rotation speed and high number of ball. A relationship between crystallinity, morphology and sorption properties was observed. (C) 2004 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
