Anomalous thermal effects in crystallization of hydrogenated amorphous alloys of the TiNi-TiCu system

Several anomalous effects not reported previously for the interaction of hydrogen with amorphous alloys of the TiNi-TiCu system have been observed, including (i) the passage from one-to multistage mechanism of the transition from the amorphous to crystalline state in hydrogenated alloys, (ii) a manifold increase in the thermal effect of glass transition in hydrogen-saturated compositions, and (iii) the appearance of an endothermal peak in the differential scanning calorimetry curves of hydrogenated alloys, which is related to the decomposition of finely dispersed hydride phases.
