Figure 4. Experimental investigations of the phase constitutions in SmCo7 samples with different grain sizes[95]: (A) as-prepared state with an average grain size of 20 nm; (B) sample annealed at 873 K for 0.5 h with an average grain size of 35 nm; and (C) sample annealed at 973 K for 0.5 h with an average grain size of 161 nm.
