Peculiarities of hydrogen absorption by melt spun amorphous alloys Nd90Fe10
Keywords:
hydrogen storage, amorphous alloys, exothermic reactions
Abstract
A fierce exothermic reaction was detected in Nd90Fe10 films with sufficient degree of amorphous phase upon filling them with hydrogen or deuterium, which resulted in the melting of the samples and the Cu foil, in which the samples have been wrapped. Quantitative analysis have shown that the amount of heat produced in large Nd90Fe10 samples in our experiments is 80÷100 kJ per g of hydrogen, which cannot be explained by DSC data on the heat produced in small samples under different heating-cooling balance. Possible reasons for the discrepancy are discussed including low energy nuclear reactions taking place at the initial stage of hydride formation.
