Abstract
A sample with nominal composition YFe10.5TiB0.5 has been prepared thro ugh careful processing. X-ray diffraction analysis revealed that the m ain phase in the sample is in the tetragonal ThMn12-type structure (sp ace group, I4/mmm),-and a small amount (less than 3%) of alpha-Fe exis ts as a second phase. Neutron diffraction measurements indicated that, in the tetragonal structure, the boron atoms occupy the 8i sites, sub stituting for a few Ti atoms, while the substituted Ti atoms enter the interstitial 2b sites. The real composition of the main phase was det ermined to be Y(Fe11.04Ti0.52B0.43)Ti-0.39.
