Correlation of microchemistry of cell boundary phase and interface structure to the coercivity of Sm(Co0.784Fe0.100Cu0.088Zr0.028)7.19 sintered magnets
Hossein Sepehri-Amin,J. Thielsch,Johann Fischbacher,Tadakatsu Ohkubo,Thomas Schrefl,Oliver Gutfleisch,Kazuhiro Hono +6 more
TL;DR: In this article, the authors revisited the microstructure of Sm2Co17-type sintered magnets to understand the underlying mechanism of substantial decrease of coercivity from 2.56 T for optimally annealed sample to 0.14 T for the sample re-annealed at aging temperature of 850 °C for just 1 min and quenched (quenched sample).
