Microstructural and magnetic studies of cast and annealed Nd and PrFeCoBZr alloys and HDDR materials
Autor: D. N. Brown, R.N. Faria, B. E. Davies, I.R. Harris
Publikováno v: Journal of Alloys and Compounds. 296:223-228
The magnetic properties of HDDR permanent magnets prepared from alloys with a nominal composition of RE 13.7 Fe 63.5 Co 16.7 B 6 Zr 0.1 (RE: Pr and Nd) have been assessed using a permeameter technique. HDDR powders from the alloy in the as-cast and a

Radioactive caesium (Cs-137), from the Chernobyl accident of 1986, has unexpectedly remained in a bioavailable form in upland, sheep-grazing soils of Great Britain. As a potential remedial measure, clinoptilolite was tested in a greenhouse pot experi

A comparative study of the sintering behaviour of NdFeB and PrFeB for permanent magnet applications
Autor: M.G. Taylor, B. E. Davies, I.R. Harris
Publikováno v: Journal of Magnetism and Magnetic Materials. :1375-1377
Liquid phase sintering plays an important role in the production of rare-earth magnets. Dilatometry has shown that Pr 16 Fe 76 B 8 , sintered in low vacuum (10 −2 bar) has a greater densification rate compared with that of Nd 16 Fe 76 B 8 . This ha

A study of the thermal demagnetisation behaviour of Nd–Fe–B sintered magnets by a magnetic field mapping system
Autor: A.J. Williams, B. E. Davies, R. Walls, J. Marchese, I.R. Harris
Publikováno v: Journal of Magnetism and Magnetic Materials. :1378-1380
A heating stage was developed for a magnetic field mapping system (MagScan). As expected, on heating of a NdFeB sintered magnet, the average field strength above the magnet decreased with increasing temperature. It was seen that the field at the cent

A preliminary electron backscattered diffraction study of sintered NdFeB-type magnets
Autor: I.R. Harris, B. E. Davies, A.J. Williams, S.J. Lillywhite
Publikováno v: Journal of microscopy. 205(Pt 3)
This paper reports, for the first time, the use of electron backscattered diffraction (EBSD) to study orientation in sintered NdFeB type magnets. The magnetic properties of NdFeB magnets are greatly improved if a strong crystallographic texture is fi
