The constitution of the alloys of Al, Fe and Si from 0 to 30% of Si and from 0 to 30% of Fe has been investigated by the methods of thermal and micrographic analysis. Seven sectional diagrams whose iron contents are respectively 1.3%, 2%, 4%, 10%, 15%, 20%, 25% and 32% of Iron have been studied and from these sections an equilibrium diagram of this system in that domain has been determined. In this diagram there exist five primary crystallization surfaces of (Al), FeAl_3, FeAl_3・FeSi_2, and χ (an unknown phase), the binary complex lines, Liquid⇌(Al)+FeAl_3 Liquid⇌(Al)+FeAl_3・FeSi_2 Liquid+FeAl_3⇌FeAl_3・FeSi_2 Liquid⇌FeAl_3・FeSi_2+Si and three invariant points, Liquid+FeAl_3⇌FeAl_3・FeSi_2+(Al) at 615℃ Liquid⇌(Al)+Si Liquid+χ⇌FeAl_3+FeAl_3・FeSi_2 Microscopically the ternary compound which has been called χ, has been proved to be FeAl_3・FeSi_2.
