• Because of the metallic glasses amorphism, they can absorb much more hydrogen than crystalic solids creating metals hydrides. So, they present hydrogen accumulators as energy carrier. Their capacity as hydrogen accumulators depends particularly on their "amorphism". Thermal stability range of metallic glasses determination is very important then. Purpose of this work was to determine the temperature range of the amorphous state stability and the effect of carbon admixture, in the presence of hydrogen on amorphous stabilization. On the basis of experimental data proved that the glass tested is thermally stable until the temperature of 600K is reached. The degrees of amorphism and crystallization as well as the size of crystallites of metastable phases were determined using the thermostimulated exoelectron emission (TSEE) and X-ray diffraction techniques. Thermal stability range of metallic glasses plays significant role in using them for storage, transport and hydrogen usage for energy industry needs (fuel cells).
