Thermal behaviour of 82Ni-18P amorphous powder alloy in hydrogen atmosphere

Abstract By the methods of differential scanning calorimetry and X-ray diffraction it was shown that chemically prepared 82Ni-18P amorphous powder alloy is an active hydrogen absorber in the temperature range 120–250 ° C, and that in the temperature range 340–450 °C it passes into the crystalline state. The processes of hydrogen absorption and crystallization were analyzed, and the kinetic and thermal parameters of both processes were determined.
