Abstract

The structural changes of stoichiometric and off-stoichiometric Ti₃Al are investigated. The analysis used a combination of X-ray diffraction, transmission electron microscopy, differential scanning calorimetry and a hydrogen analysis. It is shown that the stoichiometric Ti₃Al(Ti_0.75Al_0.25) absorbs hydrogen in the crystalline state and changes to fcc type (CaF₂)Ti₃AlH_x, but off-stoichiometric Ti₃Al(Ti_0.70Al_0.30) amorphizes by hydrogenation at room temperature.
