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 1070ºC. Comparisons between %Wtheoretical and %Wexperimental showed a satisfactory agreement.296-301openAccesshydrogenabsorptionpraseodymium alloysiron alloyscobalt alloysboron alloysniobium alloysmagnetic materialsArtigo de periódico660-66110.4028/www.scientific.net/MSF.660-661.296
