摘要：
The paper examines how a pulse current supply affects the formation of highly dispersed iron powder particles. We determine the optimum current pulse frequency (104-103Hz), the ratio of the amplitude of the nucleation current to the amplitude of the crystal growth current (In/Ig = 5:25) and the optimum ratio of the nucleation time to the crystal growth time (τn/τg = 1:10). The effect of the pulsed current manifests itself in decrease in dendricity, i.e., a reduction of the particle anisotropy, and has little impact on the powder dispersity.
