Abstract: 2024-20Si-5Fe alloy has been prepared using spray deposition technology, and secondary phases in the alloy have been investigated. Si,δ(FeSi₂Al₄),β(Fe₂Si₂Al₉) and Al₈Si₆Mg₃Fe phases have been identified in the alloy. Primary silicon, eutectic silicon andδphase exhibited a particle-like, flake-like and acicular morphology respectively. β phase came from the transformation of δ phase during hot extrusion and solution treatment. Al₈Si₆Mg₃Fe phase exhibited a small particle-like morphology as well, and dispersed in the matrix.
