Beschreibungen/Notizen

• j H c, J r and ( BH) max correlations were experimentally studied for a series of Pr x Fe 94− x B 6 alloys, with x ranging from 6 to 20 at%. The results show that the variation of the Pr content and the casting parameters yielded to j H c ranging from values near 0 to∼2200 kA/m. J r increased at the expense of j H c in agreement with some theoretical investigations related to J r/ j H c relationship. This behaviour changed for j H c values lower than ∼200 kA/m, where J r and j H c diminish together. ( BH) max showed a similar behaviour to J r up to values of j H c ∼450 kA/m (30% α-Fe) where a maximum was observed and then a decrease with reducing j H c. The results are analysed and discussed based on theoretical and experimental investigations carried out by some other workers and compared with results reported for the NdFeB system.
