The Influence of Praseodymium Content on the Hydrogen Absorption Capability of PrFeCoBNb Magnetic Alloys
The hydrogen absorption capability of PrxFe77.9-xCo16.0B6.0Nb0.1 (12.0 ≤ x ≤ 14.0) magnetic alloys was evaluated. A practical methodology was developed so that the hydrogen pressure decrease inside a closed system was correlated to the mass gain (%W) of the sample. %W increases linearly with the Pr concentration in the magnetic alloy either in the as-cast state or annealed during 20 hours at 1070°C. Comparisons between %Wtheoretical and %Wexperimental showed a satisfactory agreement.
