抄録

A unique entangled duplex structure was formed in rapidly solidified Cu–Fe–Zr–B alloys with Cu/Fe ratio = 1/1 and 6/1. Polycrystalline globules, embedded in a Cu crystalline matrix, were also observed in Cu₃₅Fe₃₅Zr₁₀B₂₀ and Cu₆₀Fe₁₀Zr₁₀B₂₀ alloys; this rapidly solidified structure was drastically different from that of Cu–Fe–Zr–B alloys enriched in Fe. Multi-step liquid phase separation can lead to unique microstructure formation during rapid solidification.
