摘要：
The influence of hydrogen saturation temperature on the structure and phase composition of the melt-spun Ti30Zr45Ni25 alloys, heat-treated in hydrogen atmosphere at different temperatures (400, 450, 500 degrees C) for 4 hours, was studied. Using X-ray diffraction analysis it was found that hydrides, formed during the hydrogenation process, were based on the Laves phase L-TiZrNi and (Ti, Zr)(2)Ni, alpha-(Ti, Zr) phases. Structural models of these phases were constructed and a model for filling these phases with hydrogen was presented. Electron microscopic study showed that the surface of the samples had no significant changes during the hydrogenation process. Also, it was established the influence of the hydrogenation temperature on the concentration of oxygen and nitrogen gas impurities in the samples.
