TiH2 and MgH2 have been synthesized by Reactive Mechanical Alloying (MA in H2 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 α-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 3d-element. X-ray diffraction was applied successfully to determine the quantity of MgH2 formed.
