摘要：

TiH2 and MgH2 have been synthesized by Reactive Mechanical Alloying CMA in H-2 or RMA) at room temperature starting from Ti and Mg powders. Ultrafine powder of TiH2 was obtained after short milling time (<1 h for Ti powder and <5 h for Ti sponge). A complete conversion of alpha-Ti to TiH2 was achieved, RMA of Mg powder only lead to a partial conversion of Mg to MgH2. However the ratio MgH2/Mg can be improved by increasing the milling time or by adding a Sd-element. X-ray diffraction was applied successfully to determine the quantity of MgH2 formed.
