摘要：

This study confirms that the stable icosahedral quasicrystal (iQc) phase Al65Cu20Fe15(iQc-AlCuFe) can serve as a substrate for the nucleation of the metastable iQc-AlMnSi phase formed in rapidly solidified Al-Mn-Si alloys. The results reveal that a continuous, thin layer of the metastable iQc-AlMnSi phase can be formed on a stable iQc-AlCuFe particle. Electron backscatter diffraction patterns and selected-area electron diffraction patterns confirmed that epitaxy exists between the stable and the metastable iQc phases. (C) 2018 Acta Materialia Inc.
