Mechanical alloying of Al70Pd20Mn10 elemental powder mixture

Some Aspects of Stability and Nanophase Formation in Quasicrystals during Mechanical Milling

“…The formation of the icosahedral quasicrystalline phase in mixed Al, Cu, and Fe elemental powders with A1 65 Cu 20 Fe 15 composition has been reported under certain milling conditions that undergo a structural change during annealing 78. Several reports have been published on the formation of the icosahedral QC phase by MA and subsequent annealing in the Al‐Cu‐Fe system 79–88.…”

Quasicrystalline phase formation in the mechanically alloyed Al–Cu–Fe system

“…It has been widely reported [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34] that QC phases can be obtained by means of MA in different systems and, in particular, the Al-Cu-Fe system has attracted particular attention because it can form a thermodynamically stable QC phase [30][31][32][33][34]. In our recent papers we report that the combination of MA and subsequent heating of Al-Cu-Fe powder mixtures results in the formation of a single-phase icosahedral QC structure [35][36][37][38][39].…”

Nanostructured icosahedral phase formation in Al70Cu20Fe10 by mechanical alloying: Comprehensive study

“…13 Earlier experimental results on mechanically alloyed Al 65 Cu 20 Fe 15 showed that the QC phase with icosahedral symmetry does not form directly during ball milling. 14 Asahi et al [15][16][17] observed the formation of the i phase along with an unknown impurity phase after subsequent heat treatment. But, most of these studies were restricted to Al 65 Cu 20 Fe 15 composition.…”
