Summary:In this work, thermal evolution of bulk nanoquasicrystalline Al93Fe3Cr2Ti2 material, obtained by consolidation of nanoquasicrystalline powder particles, is studied. The powder particles were obtained by gas atomization and the consolidation of the powders was achieved via warm extrusion [1] and [2]. The evolution of the microstructure during processing as well as with further thermal treatments was investigated. The consolidated material contains spherical particles of an icosahedral i-phase of around 200nm in diameter. The quasicrystalline phase is detected even after 1h at 500 deg C, and afterwards, it evolves through a metastable Al6Fe phase to the equilibrium phases.
