The　effect　of　Si　addition　on　phase　separation　and　soft　magnetic　properties　of　[Cu-0.6(FeCrC)(0.4)]100-Si-x(x)　(x　=　3　and　8)　immiscible　composites　produced　by　laser　induction　hybrid　cladding　(LIHC)　has　been　investigated.　The　duplex　structure　of　immiscible　composites　was　composed　of　many　Fe-rich　particles　dispersed　within　Cu-rich　upper　layer　and　large　amounts　of　Cu-rich　particles　embedded　within　Fe-rich　lower　layer.　However,　the　increasing　Si　addition　not　only　induced　the　precipitation　of　intermetallic　compound　Cu6.69Si　within　Cu-rich　upper　layer,　but　also　increased　the　area　of　Fe-rich　layer,　the　size　of　Fe-and　Cu-rich　particles,　as　well　as　the　solubility　of　Si　in　Fe-and　Cu-rich　phases.　Moreover,　the　microhardness　of　Fe-and　Cu-rich　layers　was　increased　to　747.3HV(0.2)　and　302.6HV(0.2)　in　the　Cu-55.2(FeCrC)(36.8)Si-8　immiscible　composite,　respectively,　which　was　similar　to　1.6　and　similar　to　1.8　times　higher　than　that　in　the　Cu-58.2(FeCrC)(38.8)Si-3　immiscible　composite,　due　to　solid-solution　strengthening　and　dispersion　strengthening.　Compared　to　the　Cu-58.2(FeCrC)(38.8)Si-3　immiscible　composite,　the　Cu-55.2(FeCrC)(36.8)Si-8　immiscible　composite　presented　a　saturated　magnetization　of　13.7　emu/g,　relatively　lower　coercivity　of　24.9　Oe　and　higher　Curie　temperature　of　larger　than　400　K　due　to　appearance　of　ferromagnetic　alpha-Fe(Si)　phase.　(C)　2017　Elsevier　B.V.　All　rights　reserved.
