Electron microscope studies of AI-Fe-Si intermetallics in an AI-11 Pct Si alloy

Journal Article


Abstract


  • Al-Fe-Si intermetallic particles in both unmodified and highly modified sand-cast eutectic Al-11.7 pct Si-alloys were characterized using scanning and transmission electron microscopy, energy-dispersive X-ray spectroscopy, and convergent beam and selected area electron diffraction. The only two Al-Fe-Si intermetallics observed in this particular alloy are (1) "Chinese-script" morphology, consistent with a description of body-centered cubic ��-Al19Fe4MnSi2 and (2) plate-shaped, consistent with tetragona ��-Al3 FeSi2. The authors are unaware of any other characterization of ��-Al3FeSi2 using convergent beam electron diffraction (CBED) and selected area diffraction (SAD) techniques.
