Abstract

Abstract

β-phase FeSi₂ was synthesized by Field Activated Method from Fe and Si powder mixture with small addition of Cu. The synthesis, solidification and heat treatment are completed in one step by this method. This paper investigated the effect of small addition Cu on synthesis rate and microstructure. The results show that copper can dramatically increase the phase transformation rate. Holding time do not influence the amount of remainedεphase, but finger shape of Si rich regions changes with the increase of holding time.
