Determination of the crystal alignment of Pr-Fe-B magnets using the (105) x-ray pole figure
2010 - CASTRO, A.R.M.; TAKIISHI, H.; FARIA JUNIOR, R.N.; LIMA, N.B.
The crystallographic alignment of various permanent magnets has been investigated by X-ray pole figure analysis. Attempts have been made to measure the degree of alignment of these sintered magnets using the (105) reflection. It has been shown that the (105) pole figure can be used only to verify small differences in texture in magnets high degree of crystallographic alignment. A comparison between the measured and the calculated L105 index showed good agreement.
