- Abstract
- Effect of Cu content on microstructural and magnetic properties of a (Nd_(26.06),Dy_(6.51))Febal. Cu_xB_(0.97)(wt.%),(x = 0.2, 0.3, 0.4, 0.5) strip-cast was studied. The average inter-lamellar spacing in the free surface and wheel side of the strip cast increased as the Cu content increases. The grain uniformity, the grain alignment, and (00L) texture of the strip cast increased with Cu contents up to 0.4 wt.%. These microstructural changes were attributed to the decrease of the effective cooling rate of the melted alloy caused by the decrease of the melting temperature of resulting from Cu addition. Coercivity and remanence were increased because of the grain alignment and (00L)texture improvement with Cu contents up to 0.4 wt.%.
