Synthesis of SmFe5 intermetallic compound

摘要

The SmFe 5 intermetallic compound was synthesized using the melt-spinning technique. A TEM study revealed that the as-rapidly quenched SmFe 5 melt-spun ribbon consisted of fine SmFe 5 grains. Subsequent annealing at various temperatures resulted in crystal growth of the SmFe 5 grains. The SmFe 5 melt-spun ribbon annealed at 1073 K still consisted of SmFe 5 grains together with a small amount of SmFe 3 grains. The specimen annealed at 1073 K exhibited a coercivity of 1.2 kOe.
