Amorphous-to-quasicrystalline transformation in the solid state.

TLDR: La phase amorphe se transforme en etat quasi-cristallin par deux chemins: thermique et thermique assiste par faisceau d'ions a temperature ambiante.

Abstract: ${\mathrm{Al}}_{84}$${\mathrm{Mn}}_{16}$ multilayer films have been amorphized by room-temperature ion-beam irradiation. The amorphous phase was transformed into the quasicrystalline state through two routes: thermal and ion-beam-assisted thermal. The intensity of the quasicrystalline electron diffraction increases continuously with annealing between 270 and 350 \ifmmode^\circ\else\textdegree\fi{}C. Ion irradiation of the amorphous phase produces a more complete set of icosahedral diffraction lines than thermal annealing.
