摘要：
The cell boundary phase of the Sm(Co0.725Fe0.1Cu0.12Zr0.04)(7.4) commercial sintered magnet in the early stage of the isothermal heat treatment at 800 degrees C was identified to be the SmCO5 phase by the nanobeam diffraction technique. This finding contradicts the recently reported conclusion that it consists of the Sm5Co19 phase. (c) 2006 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
