摘要: Amorphous Hf2Co11B alloys produced by melt-spinning have been crystallized annealing at 500–800 °C, and the products investigated using magnetization measurements, x-ray diffraction, scanning electron microscopy. The results reveal evolution of phase fractions, microstructure, magnetic properties with both temperature time. Crystallization denoted HfCo7, which is associated development coercivity, occurs slowly 500 °C. Annealing intermediate temperatures produces mixed samples containing some HfCo7 highest values remanent coercivity. equilibrium structure 800 °C contains HfCo3B2, Hf6Co23, Co, displays soft ferromagnetism. Maximum for magnetization, intrinsic energy product among are approximately 5.2 kG, 2.0 kOe, 3.1 MGOe, respectively, indicates that significantly higher observed in crystalli...
