Abstract
The thermal changes taking place at the sites of Fe-Co metal inclusion s in synthetic diamond grains have been investigated using Mossbauer s pectroscopy on as-grown samples and samples annealed at 970-1370 K. Th e spectra show the presence of Fe-Co and (Fe-Co)-C complexes. The temp erature-dependent results suggest that the latter are due to reactions at the metal inclusion-diamond interface, and may be a signature of t he processes leading to strength loss in the grains.
