Carbon nanoparticles of fullerites and single layer nanotubes were det
ected in Fe-Ni-C, Ni-Fe-C and Fe-Ni-Co-C alloys, manufactured from pow
ders of corresponding metals and graphite. Their identification was fu
lfilled by methods of X-ray emission spectroscopy in conjunction with
scanning electron microscopy, and by high resolution transmission elec
tron microscopy. (C) 1997 Elsevier Science Ltd.
