Main studies carried out during May:

- Preparation of thin foils from Al91Mn7Fe2 ingot and melt-spun ribbons for further investigation. (The Tenupol-5 double jet electropolisher was used)
- Microscopic observation:
• Transmission Electron Microscopy
- Observation of quasicrystal-aluminium eutectic formation, confirmed by obtained 5-fold diffraction patterns, STEM analysis confirmed that is has similar composition to the quasicrystals with spherical and dendritic shape.
- Investigation of crystallographic orientation relationship between matrix and quasicrystalline phase, as a result relation i5<011>&#945; was observed in the 5-fold diffraction pattern
- Basing on analysis of quasicrystal 2-fold electron diffraction patterns quasilattice constant aR was calculated to be 0.461 nm. (which is in agreement with values obtained for quasicrystals by other researchers )
• Scanning Electron Microscopy:
- Phase and composition analysis of two recently prepared alloys
- In Al91Mn6Fe2Si1 ingot four different phases were observed:
&#945;-Al, Al6Mn, Al3(Mn,Fe) and Al4Mn.
- In Al91Mn6Fe2Zr1 ingot also 4 different phases were formed:
&#945;-Al, Al6Mn, Al3(Mn,Fe) and Al3Zr
- Preparation of melt-spun ribbons from the mentioned alloys by melt-spinning technique.
- An abstract preparation: “TEM study of the quasicrystalline phase transformation in Al-Mn-Fe melt-spun ribbon” for the 10th Multinational Congress on Microscopy (MCM 2011) in Urbino (Italy).
- Participation in seminars
performed by M.Sc. Eng. Sylwia Pawlak and M.Sc. Eng. Tomasz Kruk.
