Hybriding-dehydriding and structural properties of composite materials produced by disproportionation reactiion of Y_5Mg_24 and Y_5Mg_22.5Ni_1.5 with hydrogen

摘要

Composite materials were prepared by disproportionation reaction of Y_5Mg_24 and Y_5Mg_22.5 Ni_1.5 with hydrogen in the temperature range from 24 to 400℃. The structural features were examined by using X-ray diffraction technique, SEM-and TEM-observations, while the hybriding and dehydriding properties were studied by using a Sieverts' method and a thermo-gravimetry analysis.
