Fig.3 compares the morphology,dimensions,and distribution of Al Fe Si intermetallic particles in the microstructure of the used alloy before and after TCP processing.As shown before,these particles usually appear in two different elongated and faceted morphologies[17-19].As evident in Figs.3(a)–3(e),different Al Fe Si particles can be traced in the microstructure of the alloy before and after TCP processing.The chemical compositions of differently numbered particles shown in Fig.3 are presented in Table 1.As can be traced in this table,the chemical composition of these particles is approximately 33wt%Fe,6wt%Si,and 57wt%Al.This chemical composition is very similar to that ofα-Al Fe Si(Al8Fe2Si).As shown in Fig.3(a),three groups of Al Fe Si particles can be traced in the microstructure of the alloy before TCP processing:
