20.500.12556/RUL-152990 Heterogeneous nucleation and orientation relationships of icosahedral phase with TiB$_2$ inoculants This study confirms that crystalline TiB$_2$ particles can act as a potent site for the heterogeneous nucleation of the metastable icosahedral quasicrystalline phase (IQC) formed in cast Al-Mn-Si-Cu-Mg alloys. The results show that a primary metastable IQC phase nucleates on facets of TiB$_2$ particles. Electron backscatter diffraction patterns and selected-area electron diffraction patterns confirmed that at least five orientation relationships (ORs) exist between the stable TiB$_2$ and the metastable IQC phase. The IQC adopts different ORs with the crystalline TiB$_2$ particles to form low energy interfaces by matching close-packed planes at the interfaces. In the IQC phase, the close-packed planes are the 5-fold and 2-fold. Microstructural analyses show that inoculation has a noticeable influence on the size and distribution of the primary IQC phase, which in turn has a noticeable influence on the compressive properties of the investigated alloys. Due to their exceptional mechanical properties, these alloys could become a prime candidate for lightweight applications, especially in the automotive and aerospace industries. aluminium alloys casting heterogeneous nucleation orientation relationship icosahedral quasicrystals true false true Angleški jezik Ni določen Članek v reviji 2023-12-13 15:35:14 2023-12-13 15:35:15 2023-12-14 03:55:10 0000-00-00 00:00:00 2023 0 0 11 str.
