文摘
- •
The evolution of Cu clusters was studied by Mössbauer spectra and corresponding hyperfine field distributions.
- •
The largest number and most uniform size of Cu clusters were obtained by pre-annealing at 588 K for 10 min.
- •
The grain size of α-Fe was reduced from 17 nm to 11 nm after the optimal two-step annealing.
- •
The optimal BS and HC of Fe83B10C6Cu1 alloy by two-step annealed were 1.81 T and 3.2 A/m, respectively.
