The influence of the chemical composition on the microstructure of high
temperature Sm(Co,Fe,Cu,Zr)z magnets is examined in this study.
A completely
developed cellular preciptation structure is the key factor for a high
coercivity. Changing the chemical composition influences the microstructure
as well as the microchemistry of the precipitations.
