Abstract

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.
