| Abstract: | Flake-like Ni powders with different size were successfully fabricated by wet sand-milling of micro-sized nickel powders.The effect of milling parameters on the morphology and microstructure of the flake-like Ni powders was studied by means of X-ray diffraction(XRD) and scanning electron microscopy(SEM).The room temperature magnetic performance of the Ni flakes was evaluated.It was found that both the bead/Ni powder mass ratio and milling time played key roles in governing the microstructures of the Ni flak... |
