Figure 3 shows the microstructures of as-cast M1alloy with SC under 0,100,200 and 300 MPa.The microstructure of M1 alloy is mainly composed of primary Si,eutectic structure,coarse plate-shapedδ-Al4(Fe,Mn)Si2,long needle-shapedβ-Al5(Fe,Mn)S and bone-shapedα-Al15(Fe,Mn)3Si2 phases.The XRD spectra of as-cast M1 alloy with SC are shown in Fig.4Table 2 gives the EDX analysis results of the FRPs According to the phase diagram,during the equilibrium solidification of Al-14Si-2Fe alloy,the primaryδphase is precipitated firstly,then the previously formedδphase transforms intoβphase through peritectic reaction L+δ→β+Si,and finally the eutectic structure is obtained[19].When Mn is added into the hypereutectic Al-Si alloy with high iron content,α-Al15(Fe,Mn)3Si2phase will be formed through peritectic reaction[20].
