| Abstract | Al-Mn powder samples were prepared by the gas atomisation technique in search of a possible single grain icosahedral phase. The X-ray diffraction analysis revealed the existence of a (Sx(B-phase in addition to the orthorhombic phase and glassy Al-Mn. The (Sx(B-phase occurs as single grains and it is a rational approximant structure to icosahedral quasicrystal. This (Sx(B-phase shows pseudo icosahedral symmetry. The space group of the (Sx(B-phase is I23 and its cell dimension is 14 ĂȘA. It transforms, kinetically along with the glassy phase, to stable crystalline form under heating. |
